M8340108K4532FCD03 Description

The M8340108K4532FCD03 from Vishay is a high-reliability thick film resistor network designed for demanding applications. Part of the Military M83401/03 series, it features a 7-resistor bussed (BUS) configuration with a 45.3K Ohm resistance value and a tight 1% tolerance. Encased in a molded SIP (Single In-line Package), this through-hole component offers a 0.84W total power rating (0.12W per resistor) and operates across a wide temperature range of -70°C to +125°C. Its ±100ppm/°C temperature coefficient ensures stability in varying thermal conditions, while the 50V maximum voltage rating and 8-pin SIP with 2.54mm terminal pitch provide robust performance in compact designs.
