Chassis Mount ResistorsF20J1K25E is one of the many types of chassis mount resistors and is characterized by their ability to suppress EMI and RFI frequencies that are commonly found in automotive, communication, industrial, consumer and medical apps. They are also renowned for their superior quality and durability, making them ideal for use in challenging commercial environments.This specific resistor is designed for board mounting applications, and is typically found in parallel RC networks. It is composed of a two terminal resistor with a ring or saddle-style lead, which provide excellent performance and low profile PCB mounting characteristics. It is capable of handling both high power and low power applications, and provides good accuracy over wide range of frequencies. The F20J1K25E series of resistors offers up to 20W of power dissipation over an extended temperature range of -55°C up to +125°C. It is available in two different packages (slim line and standard), with two available mounting heights. The slim line features a 10.7mm height, and the standard width is 21.30mm, allowing for excellent heat dissipation. Additionally, it boasts an excellent self-heating temperature coefficient of 0.15%. The F20J1K25E is constructed with high-temperature epoxy and ceramic core material, with a black protective coating, providing excellent reliability and protection against vibration and environmental hazards. It also features a robust solderable and adhesiveable surface. The resistor meets a wide range of safety rating requirements, including UL 94V-0, CSA Standard 22-23-51 and EN60950-1. It also has a wide operating temperature range of -55°C to 125°C, and provides excellent thermal shock, heat shock, and damp heat reliability.In terms of working principle, the F20J1K25E utilises the basics of impedance to function. As with any resistor, the F20J1K25E is a passive two terminal component that dissipates energy (similar to a power rating) in the form of heat. Impedance is a measure of opposition to current flow and is directly related to resistance. Due to the nature of the construction of this type of resistor it permits high current flow and is ideal for use in medium to high power applications.The F20J1K25E chassis mount resistor is designed for applications in the automotive, communication, industrial, consumer and medical industries, providing an economical solution to overcome high power dissipation, EMI/RFI suppression and ESD/EMI protection. Its rugged construction, coupled with its low profile allows for excellent performance even in challenging applications, making it the go-to chassis mount resistor in these fields.
