The common ones are power supply systems, surge suppressors, security systems, motor protection, automotive electronic systems, household appliances, etc. So how do we evaluate the service life of v...Read more -
Differences Between Varistor 10D 471K and 14D 471K
The resistance value of a varistor changes with the voltage within a certain current and voltage range, and it can also be said to be a resistor whose resistance value is sensitive to voltage. Another English name for varistor is “Voltage Dependent Resistor”, abbreviated as “VDR...Read more -
Film Capacitors in LED Lights
LED lighting has become an important light source in daily life. LED lighting products include bulb lamps, fluorescent lamps, street lamps, industrial and mining lamps, etc. Some lighting products have small internal space but high temperature, so the capacitors required are also small, high temp...Read more -

Europe has vigorously developed new energy sources, issued a series of emission regulations and implemented measures to reduce carbon emissions...Read more -
What Does The 102 3KV Mean On Ceramic Capacitor
There are two printings on the ceramic capacitor, one is the nominal capacitance, and the other is the rated working voltage. What does the ceramic capacitor 102 3KV mean? Let’s talk about the two parameters respectively. 1. 102 is the capacitance value, and 102 indicates the capaci...Read more -
What Causes The Varistor To Break Down
A varistor is a resistive component with nonlinear volt-ampere characteristics. It is mainly used for voltage clamping when the circuit is subjected to overvoltage, and absorbs excess current to protect sensitive devices. The main parameters of varistors are: varistor voltage, flow capacity, junc...Read more -
