The resistor is also popular in the telecom, aerospace and defense industries. It can be used in UHF, VHF, GPS, high-altitude, and communication transceivers. It is also suitable for industrial control and instrumentation.

Working Principle

RLR07C4220FSRSL works by limiting the current flow in the circuit. The resistor is composed of two terminals, an outer casing, and a resistor material, usually a wire-wound alloy or metal. The resistor\'s value is determined by the material and length of the wire.

When a current is applied to the resistor, it passes through it and heats up the wire-wound material. This heat is dissipated in the air. The longer the wire, the more the resistance and, consequently, the more heat is dissipated. There\'s a certain amount of current that the resistor can manage before it overheats and is destroyed.

In summary, RLR07C4220FSRSL is a through hole resistor with excellent electrical insulation properties. It is used in various fields, from telecommunications to robotics. It works by limiting the current flow in the circuit, heating up and dissipating the heat in the air.
