Internal structure of high-voltage resistor
●99 high-frequency porcelain tube is used as the resistor base, which has strong heat dissipation.
●The lead-out end is a copper cap or lead welding assembly.
●The coating is made of black high-voltage insulating heat-dissipating paint that is naturally dried and then baked at high temperature.
●Small PPM, moisture-resistant and high-temperature resistant. Resistant to pulses, surges and high voltage.
●Wide resistance range, good overload performance, can meet the use requirements of high voltage, high power, no inductance, etc. at the same time.
Resistors size diagram and application areas
●Used as load resistor and discharge resistor in high-voltage electronic instruments and equipment.
●Used as current detection resistor in various switching power supplies and power drive modules.
●Used as damping resistor in the output circuit of various high-voltage power supplies.
●Various resistors in high-frequency equipment and electronic pulse equipment.
