GUS-QS0B-03-8452-D Description

The GUS-QS0B-03-8452-D is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 84.5KΩ resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads, while the gull-wing termination ensures reliable solder joints in automated PCB assembly.

GUS-QS0B-03-8452-D Features

• Precision Thin Film Technology: Offers low noise and high stability for critical analog circuits.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances enable high-density PCB layouts.
• High Power Handling: 1W total dissipation (distributed across 19 resistors) outperforms similar networks in power-intensive applications.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, ideal for industrial and automotive-adjacent systems (though not PPAP/Automotive certified).
• Strict Tolerance & TCR: 0.5% tolerance and ±25ppm/°C ensure minimal drift in precision voltage dividers or feedback networks.
• Gull-Wing SMD Termination: Facilitates automated pick-and-place processes and visual inspection.
