GUS-QS0B-03-7500-JB Description

The GUS-QS0B-03-7500-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 20-pin QSOP package integrates 19 resistors, each with a 750Ω resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers excellent stability across a wide operating range of 70°C to 125°C, making it suitable for environments with fluctuating thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in power-sensitive designs.

GUS-QS0B-03-7500-JB Features

• Compact & Robust: 8.66mm × 6.02mm × 1.47mm QSOP package with gull-wing terminals for secure SMD mounting.
• Precision Thin Film: Low TCR (±25ppm/°C) ensures minimal resistance drift under thermal stress.
• High-Density Integration: 19 resistors in a single network reduce board space and simplify routing.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Automation-Friendly: Tube packaging facilitates pick-and-place assembly processes.
• Non-Automotive/Non-PPAP: Ideal for industrial, telecom, and instrumentation applications where PPAP compliance isn’t required.

GUS-QS0B-03-7500-JB Applications

This resistor network excels in:

• Signal Conditioning: Voltage dividers, pull-up/pull-down networks in data acquisition systems.
• Impedance Matching: Precision termination for high-speed digital circuits (e.g., LVDS, USB).
• Medical Electronics: Stable performance in patient monitoring equipment due to low thermal drift.
• Test & Measurement: Calibration circuits requiring repeatable resistance values.
• Industrial Controls: Durable operation in PLC I/O modules and sensor interfaces.

Conclusion of GUS-QS0B-03-7500-JB

The GUS-QS0B-03-7500-JB combines space efficiency, thermal stability, and precision in a cost-effective thin-film solution. Its QSOP gull-wing termination ensures reliable solder joints, while the 750Ω ±5% tolerance meets general-purpose design needs. Though not RoHS-compliant, it remains a top choice for non-automotive, high-reliability applications where consistent performance outweighs regulatory constraints. Engineers will appreciate its balance of density, power handling, and temperature resilience in compact PCB layouts.
