GS4B032942BT Description

The GS4B032942BT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 29.4KΩ resistance per element with an ultra-tight ±0.1% tolerance and a low ±25ppm/°C temperature coefficient, this ceramic-based thin-film resistor network ensures exceptional stability and accuracy. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing termination, making it ideal for space-constrained PCB designs. Rated for 100V maximum voltage and 0.4W total power dissipation, it operates reliably across a -70°C to +125°C temperature range.
