GUS-QS0B-03-1003-DA Description

The GUS-QS0B-03-1003-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 100K Ohm resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust reliability in compact designs. Packaged in a tube for automated assembly, this non-automotive, non-PPAP compliant component is ideal for industrial and instrumentation applications.

GUS-QS0B-03-1003-DA Features

• Precision Thin Film Technology: Ensures low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) footprint with 0.64mm pitch gull-wing leads for high-density PCB layouts.
• High Power Handling: 1W total dissipation (0.05W per resistor) at 125°C maximum temperature.
• Stable Performance: ±25ppm/°C TCR minimizes resistance drift under thermal stress.
• BUS Circuit Designator: Optimized for bus termination and pull-up/pull-down networks.
• Non-Automotive Grade: Tailored for industrial, telecom, and test equipment where PPAP compliance is not required.
