GUS-QS0B-03-1802-GA Description

The GUS-QS0B-03-1802-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with an 18K Ohm resistance value and a tight 2% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of -70°C to +125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Packaged in a tube, this surface-mount (SMD) network features gull-wing terminals for secure PCB attachment.
