GS4A032102JAT Description

The GS4A032102JAT from TT Electronics/IRC is a high-performance 4-resistor isolated network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. This 21kΩ network features a ±5% absolute tolerance and an exceptional ±0.05% ratio tolerance, ensuring consistent performance in differential circuits. Encased in a ceramic SOIC-C series package, it offers superior thermal stability with a ±25ppm/°C temperature coefficient, operating reliably from 70°C to 125°C at derated power. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, it balances compactness (4.9mm × 5.99mm × 1.45mm) with robustness, ideal for space-constrained designs.
