19 of the 20 fastest-growing chip companies came from China

According to reports, the growth rate of the chip industry in mainland China has now exceeded that of any country and region in the world. Per the latest released information, in the past year, 19 of the 20 fastest-growing chip companies came from China. 

(Global TMT, June 21, 2022) China's chip industry is growing faster than anywhere else in the world, according to data compiled by Bloomberg.In the past four quarters, 19 of the world's 20 fastest-growing chip industry companies were from mainland China. That compares with just eight in the same period last year. From a growth rate perspective, these Chinese suppliers of design software, processors and equipment that are critical to chip manufacturing are several times larger than large semiconductor companies such as TSMC or ASML. 

 Phelix Lee, an analyst at consulting firm Morningstar, said, "The biggest potential trend is that mainland China seeks self-sufficiency in supply chains driven by epidemic control. In 2021, mainland China imported chipsets worth up to $410 billion. Chip equipment makers from overseas suppliers rose 58% last year as mainland China continued to expand capacity, which in turn boosted local business. "There is no doubt that Chinese chipmakers can achieve revenue growth in the coming years through automotive, consumer electronics and other sectors," said Phelix Lee. 

 Total chip manufacturing sales in mainland China, including manufacturing and design firms, jumped 18% in 2021 to a record high of more than 1 trillion yuan ($150 billion), according to the China Semiconductor Industry Association. No wonder now many customers say the future of electronic components will be in China.

Russia restricts rare gas exports, which may exacerbate global chip supply constraints

Russia has restricted exports of noble gas, including neon and helium, based on approved government decrees.

These gases are indispensable raw materials for the production of semiconductors.

Russia supplies up to 30% of the world's inert gases. The government document said that exports of noble gas can now only be carried out on the basis 

of the government's decision on the advice of the Ministry of Industry and Trade. This could adversely affect global chip supply.

Vasily Shpak, Deputy Minister of Industry and Trade of Russia, said on Thursday (June 2) that the policy of restricting the export of rare gases will continue 

until the end of 2022 to strengthen its position in the international market.

Helium and neon are both important components needed to make chips. Neon, in particular, plays a key role in the manufacturing of advanced semiconductors.

Ukraine, once one of the world's largest suppliers of the noble gas, produced about half of the world's neon gas before factories in Mariupol and Odesa 

were shut down by the fighting in March.

Spark told Reuters that Russia's move would provide an opportunity to "rearrange those chains that are now broken and build new ones".

The Russian government has said on May 30 that until December 31, the export of noble gases that Russia used to offer to Japan and other countries will 

only be carried out with special permission from the state.

Russia currently accounts for 30 percent of the global supply of rare gases, according to estimates by the Russian Trade Ministry.

 India's "Economic Times" (The Economic Times) said that according to a resolution of the Russian cabinet of ministers, now only the Russian government 

can decide whether these rare gases can be delivered to the outside world.

Sources told the outlet that it would be more difficult for some countries to produce electronics without Russia's neon, argon and helium.

Russia's export restrictions could exacerbate supply constraints in the global chip market. The move could allow Russia to export these gases in exchange for semiconductor imports.

Taiwan, the world's main chip-producing region, imposed restrictions on chip exports to Russia after the war between Russia & Ukraine on February 24.

The Russian Ministry of Industry and Trade has confirmed that the agreements already reached will be taken into account when making decisions on the 

export supply of these gases.

WHAT IS #SUPERCAPACITOR #ULTRACAPACITOR #FARADCAPACITOR?

Each day brings a new technical innovations, and the demand for smaller, more portable and more functional electronics. This puts pressure on power supplies 
to be light and small, run for long periods of time (i.e., have lots of energy), and meet the demands of multiple high current loads (i.e., have a high power 
capability). Simply put, these demands cannot be met by any one portable power supply.

For decades, batteries have been the preferred storage device for portable electronics, mainly because of their ability to store energy (high energy density). 
But batteries take a long time to discharge and recharge, which limits their ability to deliver power. Overcoming this power deficit is difficult, if not impossible, 
and even newer battery technologies such as lithium ion are still a poor solution for high power applications. In applications demanding high power, over-engineering the battery will rarely be the right solution, and will typically result in increased size, weight, and cost, and/or reduced cycle life and energy. 
In other words, a magic bullet is hard to find.

This power deficit is being stretched further by the explosion in the Internet of Things (IoT). These applications are usually wireless-enabled, and yet they demand ever smaller and more portable devices, with more features and functions. Wireless transmissions, even over very short distances,
 present a tremendous power challenge to the necessarily small batteries being used in IoT devices.

Supercapacitors will be a critical enabling technology for the IoT, offering a unique combination of high power and high energy, in a thin, flat and very small 
package, to improve battery performance, and in some cases, when used with an ambient energy harvesting module or rapid recharge system, replacing the 
need to use a battery at all.

What Makes Super capacitors Super?
Supercapacitors combine the energy storage properties of batteries with the power discharge characteristics of capacitors.
To achieve their energy density, they contain electrodes composed of very high surface area activated carbon, with a molecule-thin layer of electrolyte. Since the amount of energy able to be stored in a capacitor is proportional to the surface area of the electrode, and inversely 
proportional to the gap between the electrode and the electrolyte, supercapacitors have an extremely high energy density. They are therefore able to 
hold a very high electrical charge.
The high power density derives from the fact that the energy is stored as a static charge. Unlike a battery, there is no chemical reaction required to charge or 
discharge a supercapacitor, so it can be charged and discharged very quickly (milliseconds to seconds). Similarly, and again unlike a battery, because there are 
no chemical reactions going on, the charge-discharge cycle life of a supercapacitor is almost unlimited.

What is the MSL (Moisture sensitivity level) of the multilayer ceramic capacitors?

What is the MSL (Moisture sensitivity level) of the multilayer ceramic capacitors?

The MSL level of multilayer ceramic capacitors was level 1 when evaluated by our company.

However, since products compatible to reflow soldering are applicable to MSL, products dedicated to flow soldering, such as parts with leads, are not applicable.

MSL is a JEDEC standard, and is intended for the phenomenon where the cubical expansion generated by the gasification of the moisture included in the product due to the moisture absorption of the product and the reflow soldering during mounting, which results in failures. The level that expresses this risk is the "MSL" (Moisture Sensitivity Level). As the level increases, the risk becomes higher; therefore, it is necessary to prevent moisture absorption when the level reaches 2 or more. For that reason, products of level 2 or higher must go through a baking process at a fixed period, and the tape reel is packaged in an aluminum pack with a desiccant.

UF capacitors is an 27+ ISO ISO9001:2015 mfg in China, sells to Honeywell, GE Philips and Huawai.

We keep semi-stock for chip MLCC. being dedicated to offer solution for shortage.

What is the Difference between #Active and #Passive Components

Active Components:

Those devices or components which produce energy in the form of Voltage or Current are called Active Components

Examples: DiodesTransistors SCR etc…

Passive Components:

Those devices or components which store or maintain Energy in the form of Voltage or Current are known as Passive Component

Examples:  Resistor, Capacitor, Inductor etc…

In very Simple words;

·        Active Components: Energy Donor

·        Passive Components: Energy Acceptor
