GUS-QS0B-03-3652-JA Description

The GUS-QS0B-03-3652-JA 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 36.5KΩ resistance value and a tight ±5% tolerance, ensuring consistent performance across demanding environments. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability over its operating range of 70°C to 125°C, making it suitable for thermally sensitive circuits. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical performance, while the gull-wing termination ensures reliable solderability in automated SMD processes.

GUS-QS0B-03-3652-JA Features

• Compact & Robust Design: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained layouts.
• High Reliability: Thin-film technology ensures low noise and superior long-term stability compared to thick-film alternatives.
• Wide Temperature Range: Operates up to 125°C with derated power handling, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Precision Engineering: BUS circuit designator simplifies integration into bus-line applications, while the 0.64mm terminal pitch supports high-density PCB designs.
• Non-RoHS Compliance: Suitable for legacy or specialized systems where lead-free alternatives are not required.
