GS4A032102GAT

GS4A032102GAT Description

The GS4A032102GAT 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 21kΩ resistance value and a tight ±2% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range of 70°C to 125°C, making it suitable for environments with fluctuating thermal conditions. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, ideal for space-constrained designs. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network balances power handling and precision.
