GS4A034121GFT Description

The GS4A034121GFT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding circuit applications. Housed in an 8-pin narrow SOIC ceramic package, it features 4.12KΩ thin-film resistors with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring exceptional matching accuracy. With a ±25ppm/°C temperature coefficient, this network delivers stable performance across a 70°C to 125°C operating range and supports a maximum voltage rating of 100V. Its 0.1W power rating per resistor (0.4W total) and surface-mount gull-wing termination make it ideal for compact, high-reliability designs. The ceramic case enhances thermal and mechanical durability, while the SOIC footprint (4.9mm x 5.99mm x 1.45mm) ensures compatibility with standard PCB layouts.
