GS4A038660GBT

GS4A038660GBT Description

The GS4A038660GBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 866Ω and a tight ±2% absolute tolerance (with ±0.1% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range of -70°C to +125°C, making it suitable for precision circuits. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations enables reliable surface-mount assembly, while the ceramic construction enhances thermal and mechanical durability. Rated for 100V maximum voltage and 0.1W per resistor (0.4W total), it balances power handling with compactness.
