In high voltage applications, to prevent electrical breakdown, high voltage high resistance resistors with high withstand strength and high working voltage are generally used. The value of withstand voltage here is distinguished from the working voltage, not by Ohm's law, but by the unit power calculation of the resistor surface area and resistor body material. Due to their unique process and structural shape, high-voltage high-resistance resistors can withstand high operating voltages or large impulse voltages without resistor failure, such as electrical breakdown or fire jumping. Due to the conductive and non-conductive particles in the resistor, the non-conductive particles are easily activated to form a parallel resistance in high voltage environments, resulting in a non-linear relationship between the voltage and current of the overall resistor. C&B Electronics offers thick film resistor technology and solid ceramic resistor technology with low voltage coefficient, low inductance and high reliability.
