GS4B038250GBT

GS4B038250GBT Description

The GS4B038250GBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit applications. This 7-resistor BUS-configuration array offers a 825Ω resistance per element with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Housed in an 8-pin SOIC ceramic package, it features gull-wing SMD termination for reliable surface-mount assembly. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The ceramic case ensures superior thermal stability and durability, while the ±0.1mm length/height tolerances guarantee mechanical consistency for automated PCB placement.
