Chassis Mount Resistors

Chassis mount resistors, also known as printed circuit board resistors, are active electrical components used to reduce current flow, adjust signal levels, divide voltages, and terminate transmission lines. Initially they were developed in the early 1950s for use in aircraft applications; however, their popularity and application has since broadened to include communications, industrial, and other various applications.A chassis mount resistor is made of four basic components: a resistor element, a contact spring, an insulating washer, and a mounting nut. The resistor element itself is a nickel-chrome alloy, and the contact spring is made of copper which is plated in either a gold or silver finish to prevent corrosion. The insulating washers are made of either a thermosetting plastic or glass, and the mounting nut is made of either brass or steel that is nickel plated.In terms of operation, when current flows through the resistor element, it produces a voltage which is then determined by Ohm’s Law (V = I x R). As current passes through the element, it produces heat which is dissipated through the contact spring, washer, and nut. The amount of resistance a chassis mount resistor can provide is determined by the number of turns per inch of the resistor element.CJT1003R9JJ is a type of chassis mount resistor that is designed for applications where space is at a premium or where the resistor is required to handle extreme temperatures. It has a high power rating of 0.5W and an operating temperature range of -55°C to +125°C. It is constructed from a copper alloy contact spring, a nickel-chrome resistor element, and an insulating washer made from either glass or plastic, depending on the customer’s needs. The mounting nut is made out of brass and is nickel plated for corrosion resistance.CJT1003R9JJ is used in a variety of applications, including audio, power supply, lighting, signal conditioning, and telecommunications. It is a reliable and cost-effective solution for applications requiring high power and extended temperature range. It is also designed to withstand extreme temperatures and vibration, making it well-suited for those applications that require long-term performance and greater reliability.To sum up, CJT1003R9JJ is a type of chassis mount resistor which offers a reliable, cost-effective solution for high power applications requiring an extended temperature range. It is designed to withstand extreme temperatures and vibration, making it suitable for those applications that require long-term performance and greater reliability.
