GS7B031541DDT Description

The GS7B031541DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Packaged in a 14-pin narrow SOIC (SOIC-C series), this bussed network integrates 13 thin-film resistors with a 1.54KΩ resistance value and an absolute tolerance of ±0.5%. Its ±25ppm/°C temperature coefficient ensures stability across a wide operating temperature range of 70°C to 125°C, making it suitable for environments requiring thermal resilience. The device features a 0.05W (1/20) power rating per resistor and a total power rating of 0.7W, with a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and heat dissipation.
