GS4A021243JFT Description

The GS4A021243JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 124KΩ resistance and a ±5% absolute tolerance. With a ±50ppm/°C temperature coefficient, it ensures stable performance across a wide temperature range (70°C to 125°C). The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, making it ideal for space-constrained designs. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it combines reliability with robust power handling. The gull-wing termination ensures secure surface-mount assembly, while the ceramic case enhances thermal and mechanical durability.
