M8340107K1242FCD03 Description

The M8340107K1242FCD03 from Vishay is a high-reliability thick film resistor network designed for demanding military and industrial applications. Part of the Military M83401/03 series, this 6-pin SIP (Single In-line Package) device integrates five 12.4kΩ resistors in a bussed (BUS) configuration, offering a 1% tolerance and ±100ppm/°C temperature coefficient. With a total power rating of 0.6W (0.12W per resistor) and an operating temperature range of -70°C to +125°C, it ensures stable performance in harsh environments. The molded, through-hole package provides mechanical durability, while the 50V maximum voltage rating and EAR99 ECCN classification make it suitable for export-controlled designs.
