7MM Button Metal Oxide Varistor

Button Shape Surface Mount Metal Oxide Varistor 07D471K 10D511K For LED Lighting

Description Of The Button Shape Surface Mount Metal Oxide Varistor

AFT-SMD SMD Varistor series is a patented product specially developed for surface mounting. Because of
its good heat dissipation, it has the advantages of other types of SMD products, and also has high combined
wave resistance, high working voltage capability, low residual voltage, and insulation High voltage, BSMD
series are not prone to oxygen

Features Of The Button Shape Surface Mount Metal Oxide Varistor

1) Suitable for reflow soldering with surface mounting technology, and the metal pins will not drop out;
2) High anti-combined wave ability, and the impact time interval can be shortened to 10 seconds;

3) High working voltage, which is more than 30V higher than other types of varistor working voltage;

4) Low residual voltage;
5) High insulation voltage and good resistance to hot flashes;
6) The structure is small and exquisite, the top is high and low;
7) Small inductance structure with fast response;
8) High working temperature: -40℃~+125℃.

For different application voltage environments, the following pressure-sensitive combinations are
recommended to provide transient overvoltage, surge, and lightning protection for AC LED lights:

Remark

1. A series resistor before the varistor can improve the safety performance of the varistor while effectively reducing the
residual voltage;
2. For 4KV/2KA combined wave requirements, the "resistor + varistor" scheme can be adopted for low power, and the twolevel design scheme "varistor + resistance + varistor" can be adopted for high power, which can improve the ability to resist
combined waves. At the same time, the residual pressure is effectively reduced.
3. If there are special requirements for the residual voltage, in addition to the series resistor can effectively reduce the
residual voltage, the pressure-sensitive lower limit product can also be customized.
