GUS-QS0B-03-3011-JB Description

The GUS-QS0B-03-3011-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 3.01KΩ resistance (5% tolerance) and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. With a 1W total power rating (0.05W per resistor), 100V maximum voltage rating, and gull-wing termination, this network is optimized for compact, high-density designs. Its thin-film technology delivers superior accuracy and low noise, making it ideal for signal conditioning, voltage division, and impedance matching in demanding environments.

GUS-QS0B-03-3011-JB Features

• Precision Thin Film: Offers low TCR (±25ppm/°C) and tight tolerance (5%) for reliable performance.
• High-Density QSOP Package: Compact 8.66mm × 6.02mm × 1.47mm footprint with 0.64mm pitch for space-constrained designs.
• Robust Power Handling: 1W total dissipation (0.05W per resistor) derated up to 125°C.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its thin-film construction suits industrial and telecom applications.
• Gull-Wing Termination: Ensures secure surface-mount (SMD)
  attachment and compatibility with automated assembly.
• Non-RoHS: Note: Not EU RoHS compliant; verify regulatory requirements for target markets.

GUS-QS0B-03-3011-JB Applications

• Signal Processing: Precision dividers and pull-up/down networks in ADC/DAC circuits.
• Industrial Controls: Feedback networks in power supplies and motor drivers.
• Telecom Infrastructure: Impedance matching in RF modules and baseband PCBs.
• Test & Measurement: Calibration circuits requiring low drift and high stability.
• Medical Devices: Where repetitive accuracy is critical (non-automotive).

Conclusion of GUS-QS0B-03-3011-JB

The GUS-QS0B-03-3011-JB excels in high-density, precision applications where thin-film stability, compact packaging, and moderate power handling are prioritized. While not suited for automotive use, its low TCR, gull-wing SMD design, and 19-resistor integration make it a standout for industrial, telecom, and instrumentation designs. Engineers should evaluate RoHS compliance for specific regions but can rely on its TT Electronics/IRC pedigree for consistent quality in critical circuits.
