Chassis Mount Resistors

A chassis mount resistor is an electrical component composed of a resistive element in a housing that is intended to be securely installed to a chassis. These resistors are used in an electrical circuit to provide a specific voltage drop or resistance, and they come in a variety of shapes, sizes, and types. They are used in a variety of applications in both industrial and consumer electronics, such as power supplies, amplifiers, and LED lighting.

RER45F7910RC02

The RER45F7910RC02 is a chassis mount resistor manufactured by Panasonic. It is a through-hole mounting type with a 4W power rating, designed for high power density applications such as with SMPS, LED lighting, and HVAC. The housing measures 45mm in length and the body measures 10mm in diameter, with a heat dissipation area of 9.5mm x 15mm.

Application Field and Working Principle

The RER45F7910RC02 chassis mount resistor is best suited for applications requiring a high power density where space is a constraint. Its compact size and high power rating make it ideal for applications in the telecom and industrial control sectors. Additionally, this product offers superior thermal performance with a wide operating temperature range of -25°C to +125°C.

The working principle of the RER45F7910RC02 is based on Ohm\'s law, which states that the voltage across a resistor is proportional to the current passing through it. This type of resistor consists of a resistive element, typically an alloy of metals such as nickel chrome, which is connected to two terminals. When a current is passed through the resistor, a voltage drop is developed across it, which is related to the amount of current flowing through it. In this way, the resistor is able to effectively regulate the current flow and limit the voltage in an electrical circuit.

The RER45F7910RC02 is designed to provide sustained electrical performance even under high temperature conditions, making it suitable for outdoor and high temperature applications. The resistor is well-ventilated to effectively dissipate heat from the element, ensuring its longevity and reliability during operation.

The RER45F7910RC02 chassis mount resistor is a reliable, cost effective solution for many industrial applications. Its small size and high power rating make it ideal for those needing a high power density, space-constrained solution. Additionally, its superior thermal performance and wide temperature range make it suitable for many environments including outdoor, high temperature, and industrial control applications.
