GUS-QS0B-03-3002-JB Description

The GUS-QS0B-03-3002-JB 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 30K Ohm resistance and a 5% tolerance, delivering a ±25ppm/°C temperature coefficient for stable operation across a 70°C to 125°C derated power range. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it ensures reliability in demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.

GUS-QS0B-03-3002-JB Features

• Thin-Film Technology: Offers superior stability, low noise, and tight tolerance (±25ppm/°C) compared to thick-film alternatives.
• High-Density Integration: 19 resistors in a QSOP-20 package optimize space in multi-channel designs.
• Robust Power Handling: 1W total dissipation (derated to 70°C–125°C) ensures durability in high-temperature environments.
• Precision Performance: 5% tolerance and 30K Ohm values suit analog signal conditioning and voltage division.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its thin-film construction makes it ideal for industrial and telecom applications.
• Non-RoHS Compliant: Suitable for legacy systems where lead-free compliance is not required.
