M8340108M3303GCD03 Description

The M8340108M3303GCD03 from Vishay is a high-reliability, military-grade thick film resistor network designed for demanding applications. This 8-pin SIP (Single In-line Package) device features a bussed (BUS) circuit configuration with seven 330kΩ resistors, offering a total power rating of 0.84W (0.12W per resistor). With a tight tolerance of ±2% and a temperature coefficient of ±300ppm/°C, it ensures stable performance across a wide operating temperature range of -70°C to +125°C. The molded case provides robust mechanical protection, while the through-hole pin termination ensures secure mounting. Compliant with military standards (M83401/03 series), this non-automotive, non-PPAP part is ideal for precision circuits requiring durability and consistency.
