GUS-QS8B-01-8451-C Description

The GUS-QS8B-01-8451-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 8.45KΩ resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±100ppm/°C temperature coefficient, it maintains stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads.

GUS-QS8B-01-8451-C Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with gull-wing terminations for reliable SMT assembly.
• High Power Density: 0.75W total dissipation in a miniaturized footprint, ideal for space-constrained designs.
• Automotive-Grade Alternatives: While not automotive-qualified (PPAP: No), its 125°C max operating temp suits industrial and telecom applications.
• Strict Tolerances: ±0.1mm length/height tolerances ensure consistent PCB placement.
