GUS-QS0B-03-3402-JD Description

The GUS-QS0B-03-3402-JD 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 34K Ohm resistance value and a 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. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Packaged in a tube for secure handling, this surface-mount (SMD) network features gull-wing terminations for robust PCB connectivity.

GUS-QS0B-03-3402-JD Features

• Precision Thin Film Technology: Ensures low noise and high accuracy (±25ppm/°C) for sensitive circuits.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length) save board space.
• High Power Handling: 1W total dissipation (1/20W per resistor) outperforms standard networks in power density.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Robust Construction: Gull-wing leads (0.64mm pitch) enhance mechanical stability during soldering.
• Non-RoHS Compliance: Suitable for legacy systems requiring leaded components.

GUS-QS0B-03-3402-JD Applications

• Signal Conditioning: Precision voltage dividers in test equipment and data acquisition systems.
• Industrial Controls: Stable resistance networks for PLC modules and sensor interfaces.
• Telecom Infrastructure: Impedance matching in RF modules and baseband processing.
• Medical Devices: Low-drift circuits in diagnostic instruments where temperature stability is critical.
• Legacy Electronics: Repair or replication of non-RoHS-compliant designs.

Conclusion of GUS-QS0B-03-3402-JD

The GUS-QS0B-03-3402-JD excels in high-precision, space-constrained applications requiring thermal stability and moderate power handling. Its thin-film technology and QSOP packaging offer a competitive edge over thicker-film or bulkier alternatives. While not suited for automotive use, it remains a top choice for industrial, telecom, and medical electronics where reliability and compactness are paramount. Engineers will appreciate its balance of performance, durability, and ease of integration into surface-mount assemblies.
