GS4A034221GT Description

The GS4A034221GT from TT Electronics/IRC is a high-performance 4-resistor isolated network designed for precision applications. Housed in an 8-pin narrow SOIC ceramic package, it features 4.22KΩ thin-film resistors with a tight ±2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it operates reliably across a wide temperature range of -70°C to +125°C. The gull-wing termination and surface-mount design ensure compatibility with automated assembly processes. With isolated elements, this network minimizes crosstalk, making it ideal for signal conditioning and isolation circuits.
