High Voltage Resistors

The impediment to the current of the conductor is called the resistance of the conductor. High-voltage resistors are the most commonly used element in all electronic circuits. The main function is to hinder the current flow, used in current limiting, shunt, drop voltage, partial pressure, load and capacitor for the filter and impedance matching, etc. Digital circuits have pull-up resistors and pull-down resistors.

Resistors are the most used component in all electronic circuits. The main physical feature of a resistor is transferring the electrical energy to thermal energy. It can be named a dissipative component that generates internal energy when current passes through it. Resistors in the circuit usually are the role of partial pressure shunt, for the signals, both AC and DC signals can pass through the resistors.

Resistor has a certain resistance, which represents the size of the resistor's blocking force on the current flow. The unit of resistance is ohm, symbol "Ω". In the SI system, the unit of resistance is Ω, in addition to mΩ, KΩ, MΩ. Exchange formula: 1MΩ=1000KΩ=1000000Ω=1000000000mΩ.

High voltage resistors are suitable for use in high voltage, high voltage shock, high voltage and high frequency environments. Here are classification for high voltage resistors below:

1. Tubular ceramic non-inductor high voltage resistors are 100% ceramic body resistors, pure non-inductor, high voltage resistance, the maximum impact voltage is up to 75KV, can withstand greater current, higher peak energy in short times; no failure phenomenon like wire wound resistors and molded resistor.

2. High-voltage lead-free wafer resistors are sintered by using a mixture of metal oxides and ceramic materials at high temperatures. They can withstand the effect of instant high temperature and high pressure, mainly applied in cars and motorcycles ignition.

3. High-pressure metal-ceramic damping resistors have superior high-voltage high-current surge characteristics, and more stable than the wire wound resistors and film resistors. Suitable for high-voltage circuit design.

4. Oxide film high voltage high frequency resistors use tubular ends which are silver or gold electrode structure, mainly used for UHF circuit load.

5. Rod-shaped high voltage glass glaze film resistors are mainly used in AC or DC circuits, pulse circuit and high-voltage equipment.

6. Flake high voltage glass glaze film resistors are mainly used in AC and DC circuits, pulse circuits and high-voltage equipment.
