M8340108K1782FGD03 Description

The M8340108K1782FGD03 from Vishay is a high-reliability thick film resistor network designed for precision applications in demanding environments. Part of the Military M83401/03 series, this 8-pin SIP (Single In-line Package) device features four isolated 17.8KΩ resistors with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient. Its molded construction ensures durability, while the through-hole mounting provides mechanical stability. With a 0.48W total power rating (0.12W per resistor) and a 50V maximum voltage rating, it operates reliably across a wide temperature range of -70°C to +125°C. The 2.54mm terminal pitch and 19.89mm package length make it compatible with standard PCB layouts.
