GS4B0257R6DDT Description

The GS4B0257R6DDT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for surface-mount applications. Housed in an 8-pin SOIC ceramic package, it offers a 57.6 Ω resistance per resistor with a tight ±0.5% tolerance and a low ±50 ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The BUS circuit designator indicates its suitability for bus termination and signal conditioning. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances performance and reliability in compact designs. The gull-wing termination and 1.27mm pitch facilitate easy PCB integration.
