Chassis Mount Resistors

A chassis mount resistor is an electrical component designed to provide electrical resistance in electrical and electronic circuits. This type of resistor is usually used in industrial applications where there is a need for higher heat capacity or mechanical strength than a standard axial lead resistor is able to provide. These resistors are typically constructed of a cermet material, and can be mounted to a variety of substrates including printed circuit boards, machine chassis, or automotive body panels. The most common types of chassis mount resistor are HS300 680R J, which is a type of non-inductive, axial lead-style resistor.

Application Field

HS300 680R J chassis mount resistors are typically used in applications that require an array of resistors on a single substrate, often at a relatively close distance from each other. This type of resistor is designed to dissipate high amounts of heat from multiple points on the substrate, and is often found in applications such as power supplies, audio equipment, amplifier circuits, LED lighting systems, and any other situation where multiple resistors are required in a small space. Chassis mount resistors can also be used to balance current loads between two or more components in an electrical circuit.

Working Principle

The working principle of the HS300 680R J chassis mount resistor is relatively simple. As an electrical current is applied, the voltage across the resistor increases, and the corresponding amount of electrical power is dissipated as heat. The resistor is designed to first limit the current passing through the circuit and then dissipate it in the form of heat. The heat generated by the resistor is transferred via conduction to the substrate it is mounted on, and thus is removed from the electrical circuit.

The HS300 680R J chassis mount resistor is highly efficient in its operation. This is due to its design which allows it to dissipate heat to a larger area across the component’s substrate. Additionally, its ability to mount on different substrates means it can be used in applications where a standard axial lead resistor cannot. As a result, the HS300 680R J chassis mount resistor is often used in the design and construction of automotive, industrial, and consumer electronics.

In summary, the HS300 680R J chassis mount resistor is an electrical component used to provide electrical resistance in a variety of applications. It is mainly used for industrial applications where the need for higher heat capacity or mechanical strength is necessary. The working principle of the resistor is to limit the current passing through the circuit and then dissipate it in the form of heat, and its design allows it to dissipate heat to a larger area. As a result, the HS300 680R J chassis mount resistor is often used in the design and construction of automotive, industrial, and consumer electronics.
