GS4A021780JCT Description

The GS4A021780JCT 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 178Ω resistance and a ±5% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating range of -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. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, it balances power handling and reliability. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the ceramic case enhances thermal and mechanical durability.
