Working Principle

The working principle of the H4187RDYA through hole resistor is simple: it limits the flow of electrical current by creating a large resistance to the electrical current. The amount of resistance depends on the design of the resistor and the materials used. The H4187RDYA is made of an aluminum core covered with an insulating layer of a special silicone rubber. This rubber layer acts as a barrier between the current and the metal cores, which prevents any short circuits.

When the electrical current passes through the H4187RDYA through hole resistor, the metal cores within the resistor warm up until they reach a constant temperature. The resistance of the resistor varies depending on the amount of current flowing through it. By adjusting the amount of current flowing through the resistor, it is possible to control the power output.

Conclusion

The H4187RDYA through hole resistor is a reliable and economical choice for anyone looking to control the flow of electrical current. It is easy to install and provides excellent power dissipation, low noise, high frequency stability, and accuracy. This makes it an ideal choice for a variety of automotive, home theater, lighting, audio, and general purpose electronic applications.
