GUS-QS0B-03-1271-B Description

The GUS-QS0B-03-1271-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 1.27KΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy. The network operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, making it suitable for harsh environments. Its thin-film technology delivers a low ±25ppm/°C temperature coefficient, minimizing resistance drift. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust performance in compact designs. Packaged in a tube, this surface-mount component features gull-wing terminals for reliable PCB attachment.
