GUS-QS0B-03-2702-B Description

The GUS-QS0B-03-2702-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 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, making it suitable for harsh environments. Its ±25ppm/°C temperature coefficient guarantees stable performance under thermal stress. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in precision circuits.
