GUS-QS0B-03-2671-C Description

The GUS-QS0B-03-2671-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 2.67KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The non-automotive, non-PPAP compliant device is supplied in tubes for efficient assembly handling.

GUS-QS0B-03-2671-C Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.25%) and low TCR (±25ppm/°C) for signal conditioning and voltage division.
• Robust Construction: QSOP package (8.66mm × 6.02mm × 1.47mm) with ±0.1mm length/height tolerances ensures mechanical reliability.
• High Power Density: 1W total dissipation (0.05W per resistor) at 125°C max operating temperature, ideal for thermally constrained environments.
• Optimized for SMT: 0.64mm terminal pitch and gull-wing leads enable seamless automated placement.
• Non-RoHS (Not Compliant): Suitable for legacy or specialized industrial systems requiring leaded components.

GUS-QS0B-03-2671-C Applications

• Precision Analog Circuits: Voltage references, DAC/ADC interfaces, and feedback networks in test equipment.
