PR02000202000JR500 Resistor: Working Principle, Datasheet and Features

PR02000202000JR500 Description

The PR02000202000JR500 is an axial leaded resistor constructed with a homogeneous metal alloy film deposited on a premium ceramic substrate. A helical groove is precision-cut into the resistive layer to define the resistance value, and the component is completed with tinned copper or copper-clad iron leads welded to end-caps for secure electrical connection. It features a durable red, non-flammable lacquer coating that offers protection against electrical, mechanical, and environmental stresses. 

While the coating is not resistant to aggressive fluxes or cleaning solvents, the internal encapsulation meets IEC 60068-2-45 standards for solvent resistance.

PR02000202000JR500 Working Principle

The working principle of the PR02000202000JR500 is based on the fundamental characteristics of metal film resistors. A uniform layer of metal alloy is deposited onto a high-grade ceramic substrate to form the resistive element. During manufacturing, a helical groove is cut into the resistive film to precisely adjust the resistance value. As current passes through the metal film, it encounters resistance, thereby enabling functions such as current limiting and voltage division.

The leads are made of electrolytic copper or copper-clad iron and are welded to the end caps, ensuring reliable electrical connections. The resistor is coated with a red, flame-retardant lacquer, which enhances protection against mechanical stress and environmental influences.
