CA42
CA42 Radial Tantalum Capacitor is a professional grade device manufactured with a flame retardant coating and featuring low leakage current and impedance, very small physical sizes and exceptional temperature stability. It is designed and conditioned to operate to +125°C (see page 2 for voltage derating above 85°C) and is available bulk and Ammo taped for auto insertion. The 6 sizes with wide capacitance and working voltage ranges means the CA42 series can accommodate lots of applications. CA42 is a perfect replacement of AVX TAP series (please refer to Topdiode cross guide). CA42 is designed for industrial use. Military radial tantalum capacitor is available on request.
CA45
CA45 Chip Tantalum Capacitor is a general purpose SMT chip tantalum series. CA45 can replace Kemet T491, AVX TAJ, and Vishay 293D Series.

Silicon carbide has a high thermal conductivity and temperature has little influence on its switching and thermal characteristics. With special packaging it is possible to have operating junction temperatures of over 500 K, which allows passive radiation cooling in aerospace applications.
The Schottky diode (named after German physicist Walter H. Schottky; also known as hot carrier diode) is a semiconductor diode with a low forward voltage drop and a very fast switching action. The cat's-whisker detectors used in the early days of wireless can be considered primitive Schottky diodes.
When current flows through a diode there is a small voltage drop across the diode terminals. A normal silicon diode has a voltage drop between 0.6–1.7 volts, while a

Storage of capacitors
Aluminum electrolytic capacitors
Storing aluminum electrolytic capacitors at high temperatures or in direct sunlight will cause the electrolyte within the capacitor to evaporate through the rubber end seals. The loss of electrolyte through accelerated evaporation causes the capacitance to decrease and increases in the dissipation factor, ESR and leakage current. The life expectancy of the capacitors will also be decreased. The solderability of the capacitors can also be compromised.
Do not store aluminum electrolytic capacitors in wet or humid conditions or outdoors. Storing capacitors in moist conditions can corrode the lead wires which can prevent the capacitors from soldering properly.
Storage in oil, ultraviolet ray, ozone and radiation will cause the deterioration of the rubber end seals causing the capacitors end seals weaken resulting in the reliability of the capacitors to be compromised.
Storing aluminum electrolytic capacitors should between +5°C and +40°C with 75% relative humidity and indoors.
Storing aluminum electrolytic capacitors should also be limited to 2 years after which time the capacitors should be checked for compliance to specifications. If the capacitors have any specification out of specification the capacitors can be reconditioned. After reconditioning the capacitors can be stored up to 2 additional years. Capacitors that have been stored for over 2 years after reconditioning should be scrapped and new parts should be used.
Film capacitors
Film capacitors like aluminum electrolytic capacitors should be stored under controlled conditions to prevent any deterioration of the capacitors. Film capacitors should be stored in similar conditions to aluminum electrolytic capacitors except film capacitors can be stored for many years before they will drift out of specifications.

Topdiode Declaration of Metal Conflict-Free
Topdiode Manufacturing is taking and will take due diligence within our supply chain to assure “DRC Conflict-Free” for the metals of gold(Au), tantalum(Ta), tungsten(W), cobalt(Co) and tin(Sn) are not derived from or sourced from mines in conflict areas of the Democratic Republic of Congo (DRC), or illegally taxed on trade routes, either of which are controlled by non-governmental military groups, or unlawful military factions. Trade routes not confirmed to be “Conflict Free” include direct exports from the DRC, as well as exports through Rwanda, Uganda, Burundi, Tanzania and Kenya (countries of whom the U.N. Security Council note are global export routes for DRC-mined minerals).
Topdiode declare the metal Conflict-Free on all products (diode, bridge, transistors) which listed on website http:// www.topdiode.com

1 Amp Rectifier for Every Need （M7 1N4007
1Amp rectifiers are the "workhorses" in a lot of electronic applications. These products are used to do the rectification of the mains voltage
and are usually only loaded with 100 milliAmps.
While the 1N4007 was formerly the state of the art for such applications, now Surface Mount versions (SMDs) are in a much wider use.
In order to react to the always changing demands of the market and our customers, we at Topdiode are pleased to invite you to check our 1 Amp
Rectifiers below.
