GUS-QS0B-02-4702-BA Description

The GUS-QS0B-02-4702-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 47K Ohm resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Housed in a 20-pin QSOP package with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch for high-density PCB layouts. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines precision with robustness.

GUS-QS0B-02-4702-BA Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and ±50ppm/°C TCR for critical analog circuits.
• High-Density Design: QSOP package with 20 gull-wing pins optimizes board space in compact designs.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power up to 125°C).
