GS4A0368R1DT

GS4A0368R1DT Description

The GS4A0368R1DT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC ceramic package, it features 68.1Ω thin-film resistors with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated circuit design (ISOL) allows independent resistor operation, making it ideal for precision signal conditioning. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, it balances performance and reliability in compact designs. The gull-wing termination and surface-mount (SOIC) package ensure easy PCB integration, while its ceramic case enhances thermal and mechanical durability.
