GUS-QS8B-02-4121-C Description

The GUS-QS8B-02-4121-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 with a 4.12KΩ resistance value, offering a tight tolerance of ±0.25% and a low temperature coefficient of ±50ppm/°C. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it operates reliably across a -55°C to +125°C temperature range. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.

GUS-QS8B-02-4121-C Features

• Precision Performance: Thin-film technology delivers ±0.25% tolerance and ±50ppm/°C TCR, ideal for analog signal conditioning.
• Robust Power Handling: 0.75W total dissipation (0.05W/resistor) with a 100V maximum voltage rating.
• Compact & Reliable: QSOP package with 0.64mm terminal pitch for high-density layouts; ±0.1mm height tolerance ensures consistent placement.
• Wide Temperature Range: Operates from -55°C to +125°C (derated power up to 125°C).
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation applications (PPAP not required).

GUS-QS8B-02-4121-C Applications

• Precision Voltage Dividers: Critical in ADC/DAC reference circuits due to low TCR and tight tolerance.
• Medical Equipment: Stable performance in patient monitoring systems and diagnostic tools.
• Test & Measurement: High accuracy in oscilloscopes and multimeters.
