Through Hole Resistors

Through hole resistors are a type of resistor with leads that are inserted through a metal circuit board and soldered into place. They are widely used in electronic applications that require a low input resistance. Popular applications include AC line filtering and power conditioning, noise and EMI suppression, and impedance matching.

The H890R9DZA is a through hole resistor that is specifically designed and manufactured for high power applications. It is a compact, surface mount resistor with an integrated heat sink that is capable of operating at power levels up to 100 Watts. The resistor features a welded, oxide-coated case for superior thermal performance and durability, and a thick film construction that provides excellent power stability and reliability.

Application Field

The H890R9DZA is a versatile resistor that can be used in a variety of applications, such as high power filtering for AC and DC systems, interference and EMI suppression, radio frequency protection, power management and impedance matching.

Due to its robust construction, the H890R9DZA is ideal for use in high power audio applications such as amplifiers, receivers and speakers. It is also suitable for use in medical, industrial, and automotive applications, as well as instrumentation and power supplies.

Working Principle

The H890R9DZA works by converting electrical energy into heat energy through Ohmic resistance. When a current is passed through the resistor, a voltage drop will develop across it, resulting in a corresponding power loss in the form of heat. This is known as Joule heating, and is used to dissipate excess heat away from sensitive components.

The H890R9DZA is designed to minimize the amount of heat that is generated. Its thick film construction and welded oxide-coated case provide superior thermal performance, allowing it to operate up to 100 watts without overheating.

In addition, the resistor\'s integrated heat sink allows the resistor to be mounted directly to the printed circuit board, eliminating the need for additional mounting components. This ensures that the resistor is properly cooled and dissipates heat quickly and efficiently.

The H890R9DZA is a reliable and versatile resistor that is ideal for high power applications. It is compact, durable, and capable of operating at power levels up to 100 watts, making it perfect for a variety of electronic applications.
