GS4A021910JCT Description

The GS4A021910JCT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 4-resistor isolated network features a 191Ω resistance per element with a ±5% absolute tolerance and an exceptional ±0.25% ratio tolerance, ensuring consistent performance in matched circuits. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. The thin-film technology delivers a low ±50ppm/°C temperature coefficient, stable across a 70°C to 125°C derated power range, and supports a maximum operating temperature of 125°C. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, it balances durability and efficiency.
