GUS-QS0B-03-2701-JD Description

The GUS-QS0B-03-2701-JD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 19-resistor array features a 2.7KΩ resistance value per element with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature 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, making it ideal for high-density layouts. Rated for 100V maximum voltage and 1W total power dissipation (0.05W per resistor), this non-automotive, non-PPAP compliant component is supplied in tube packaging for efficient handling.

GUS-QS0B-03-2701-JD Features

• Thin-Film Technology: Delivers superior accuracy (±25ppm/°C TCR) and long-term stability compared to thick-film alternatives.
• High-Density Design: QSOP package with 20 gull-wing terminals optimizes board space in multi-channel circuits.
• Robust Power Handling: 1W total rating (1/20W per resistor) supports moderate-power applications without derating.
• Wide Temperature Range: Operates reliably from 70°C to 125°C, suitable for industrial and telecom environments.
• Precision Tolerance: 5% resistance tolerance ensures consistent performance in voltage division and signal conditioning.
• Non-Compliant with EU RoHS: Note for applications exempt from RoHS restrictions.

GUS-QS0B-03-2701-JD Applications

• Analog Signal Processing: Ideal for DAC/ADC reference networks, gain setting, and feedback loops in precision instrumentation.
• Voltage Division: Used in sensor interfaces and measurement systems requiring stable divider ratios.
• Industrial Controls: Suitable for PLC modules, motor drivers, and power management circuits due to its thermal resilience.
• Telecom Infrastructure: Deployed in filter networks and impedance matching for RF/baseband PCBs.
• Legacy Systems: Non-RoHS compliance makes it a fit for military/aerospace or exempt commercial repairs.

Conclusion of GUS-QS0B-03-2701-JD

The GUS-QS0B-03-2701-JD excels in space-constrained, precision analog designs where thin-film stability, moderate power handling, and high pin-count density are critical. While not suited for automotive or RoHS-mandated projects, its wide temperature range and low TCR make it a standout choice for industrial, telecom, and legacy systems. Engineers will appreciate its balance of performance and compactness, particularly in multi-channel signal chains requiring repeatable resistance matching.
