IRC's WCR series resistors are designed for general-purpose applications requiring high reliability and a broad selection of resistance values. These surface-mount resistors feature a high alumina substrate with a ruthenium oxide resistance element and silver-palladium, nickel, and tin-plated terminations. They are Pb-free, compliant with RoHS directives, and available in various sizes (0201, 0402, 0603, 0805, 1206, 1210, 2010, 2512) to accommodate different design requirements. The resistors are marked with a three-digit code indicating significant figures and added zeros, ensuring easy identification. They exhibit excellent solvent resistance and are suitable for use in a wide range of industrial cleaning fluids. The WCR series is ideal for applications in automotive, industrial, and consumer electronics where precision and reliability are paramount.
