Through Hole Resistors: H469K8BDA Application Field and Working Principle

Resistors are an essential element in the majority of electronic circuits. Through hole resistors are one of the wider categories, and they range in type, power, and composition. This paper will discuss the H469K8BDA metal film resistor, an example of a low cost, high accuracy, and highly reliable resistor. We will review its application fields and working principles, and how engineers can incorporate this device into their designs.

What is a Through Hole Resistor?

A through hole resistor is a type of resistor with two terminals connected to a dielectric material. The two terminals are typically spaced apart, which allows for the electrical current to pass through the terminals. It is designed to resist the flow of electrical current in a circuit. Depending on the design of the resistor, through hole resistors can also be used to lower the voltage, limit the current, or set the impedance of a circuit.
