Through Hole Resistors

A through hole resistor is an electronic component that uses a resistive element to reduce the current flow through a circuit. Through hole resistors are widely used in a variety of electronic devices and circuits in order to achieve a desired level of resistance. The most common types of through hole resistors are wire-wound, cermet, and metal film.

H893R1BCA Application Field and Working Principle

The H893R1BCA is a through-hole resistors from ABB. It features a fixed resistive element made from metal film construction and is available in five different power ratings of 0.12W, 0.25W, 0.5W, 1W, and 2W. The H893R1BCA also has a high temperature coefficient, ensuring that the resistive value of the component remains relatively stable despite changes in temperature.

The H893R1BCA is mainly used in applications where accurate and stable resistance values are required over a wide temperature range. These applications include audio systems, electro-mechanical circuits, power supplies, and instrumentation. For example, in audio systems, these resistors help to stabilize the level of output signal and reduce electrical noise.

The H893R1BCA has a simple and yet effective working principle. The resistor’s resistive element (the metal film) consists of a series of metal strips placed in an electrically conductive material. When a current is applied to the resistor, the current will encounter resistance as it passes through the metal strips. This resistance is what governs how much current is allowed to flow through the resistor. By varying the size of the metal strips and the amount of material used, the resistor manufacturer can accurately adjust the resistance value of the component.

The H893R1BCA is designed to function reliably and accurately over a wide range of temperatures, thanks to its combination of a specialized metal film and stable construction materials. This type of resistor is perfect for applications in which temperature variations can cause instability in the value of the resistance.

The H893R1BCA is just one example of a through-hole resistors from ABB. This type of component is used in a variety of applications due to its combination of accurate resistance values, reliable performance, and wide temperature range.
