GS4A033740GFT Description

The GS4A033740GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 374Ω resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched circuits. Its thin-film technology delivers a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. The device operates within a -70°C to +125°C range, derated for power, and supports a maximum voltage rating of 100V. With a 0.1W power rating per resistor (0.4W total), it balances compactness and reliability in space-constrained designs.
