Working Principle

When a voltage is applied to the resistor, electrical energy is dissipated in the form of heat. As the resistor heats up, the resistance varies slightly, due to the difference in electrical conductivity of the ceramic material. This is known as "thermal coefficient of resistance", and allows the resistor to maintain a fairly constant resistance, even when exposed to temperature changes.The resistor also has a fairly low current development factor, which is the rate at which current is developed in the resistor. This helps to reduce the amount of energy lost in the form of heat.The resistor also has a low level of inductance, which helps to reduce transients that can be generated during the operation of the system. As a result, the H8422RDZA through-hole resistor is well suited for applications requiring high accuracy and reliability.
