GUS-QS0B-03-4642-JA Description

The GUS-QS0B-03-4642-JA 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 a 46.4KΩ resistance value and a tight 5% 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, making it suitable for demanding environments. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its robustness in circuit designs. Packaged in a tube for automated assembly, this surface-mount (SMD) component features gull-wing terminals for secure PCB attachment.

GUS-QS0B-03-4642-JA Features

• Precision Thin Film Technology: Ensures low noise and high accuracy for sensitive analog/digital circuits.
• Compact QSOP Package: 8.66mm (L) x 6.02mm (D) x 1.47mm (H) footprint saves board space in dense layouts.
