GS4A033902JGT Description

The GS4A033902JGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values across varying temperatures. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 39 kΩ resistance and a ±5% absolute tolerance. The device operates within a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. Its ±25 ppm/°C temperature coefficient ensures minimal resistance drift, while the 0.1W (1/10W) power rating per resistor (0.4W total) provides reliable performance in compact designs. The SOIC-C series construction offers excellent thermal stability and low noise, ideal for analog signal conditioning and voltage division circuits.
