GS4B033740DT Description

The GS4B033740DT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. This 7-resistor bussed network features a 374Ω resistance value with an ultra-tight ±0.5% absolute tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing termination for reliable PCB mounting. The thin-film technology provides excellent power handling (0.4W total, 0.05W per resistor) and a maximum voltage rating of 100V, making it suitable for precision analog and digital circuits.
