Through Hole Resistors

The H42K2DZA is a through-hole resistor, which adds resistance to an electrical circuit. It is constructed of a ceramic material wound with copper wire. The resistance of a through hole resistor is determined by the thickness of the copper wire. The higher the thickness, the higher the resistance.

Application Field

Through-hole resistors are commonly used in the automotive, industrial, and aerospace industries. In the automotive industry, they are primarily used for powertrain applications such as fuel injection and electrical systems. They are also used in industrial circuits for electrical motors, temperature controls, and power supplies. In the aerospace industry, they are used in avionics systems and in spacecrafts for power and navigation systems.

Working Principle

A through hole resistor works by limiting the flow of electricity in a circuit, providing electrical resistance to the circuit. This principle is called ohms law, which states that “the resistance of a resistor is equal to the voltage of the resistor divided by the current”. This means that when the voltage increases, the current decreases and vice versa. The H42K2DZA resistor has a resistance of 4.2k Ohms, meaning it requires 4.2 Volts to pass 1 Amp of current.

The resistance of a through hole resistor is determined by the thickness of its copper wire. For the H42K2DZA, the copper wire has a thickness of 0.2mm, providing the necessary 4.2k Ohm resistance. This means that the resistance of the resistor will remain constant, regardless of the voltage applied to it. As such, through hole resistors are a reliable source of resistance in a circuit.

Through-hole resistors are also much more durable and reliable than other types of resistors. As a result, they are commonly used in applications where reliability and durability are critical such as automotive, industrial, and aerospace applications.
