Through Hole Resistors

Through hole resistors are one of the most widely used passive components in the electronics industry. They are used in the creation of various electrical circuits, such as power supplies and amplifiers.

The H4178RBDA is a non-inductive, surface-mount resistor developed for use in high-frequency applications. It utilizes two precision resistor elements placed on opposite surfaces of a phenolic insulation disk. The resistor elements are protected within a sealed ceramic enclosure that allows the device to be mounted directly on printed circuit boards. This type of resistor delivers superior performance over a wide range of temperatures and frequencies.

Application Field and Working Principle

The H4178RBDA is particularly suitable for applications involving high power dissipation and frequency. This type of resistor can be used in a variety of applications, including audio equipment, car stereo systems, industrial inverters, and consumer electronics.

The H4178RBDA works by utilizing two precision resistor elements placed on opposite sides of a phenolic insulation disk. The two resistor elements are protected by a sealed ceramic enclosure, which allows the device to be easily mounted on printed circuit boards. This type of resistor operates by generating an electrical field in the space between the two resistor elements. When a current is applied across the resistor elements, the electric field creates an electrical impedance between the resistor elements, resulting in the desired resistance. This type of resistor also offers excellent stability over a wide range of temperatures and frequencies.

The H4178RBDA is a popular choice for many electronic applications due to its high power dissipation capabilities and frequency response. It is suitable for use in a variety of applications including automotive, industrial, and audio equipment. Its ability to generate a stable and reliable electrical field between the two resistor elements allows this type of resistor to provide an excellent level of performance even in the most demanding environments.
