GUS-QS8A-03-2493-DB Description

The GUS-QS8A-03-2493-DB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull wing terminations, this device offers a 249K Ohm resistance per isolated resistor with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 0.1W (1/10W) per resistor, it operates reliably across a 70°C to 125°C derated temperature range, with a maximum operating temperature of 125°C. Its 100V maximum voltage rating and thin film technology ensure stable performance in precision circuits.

GUS-QS8A-03-2493-DB Features

• High Precision: 0.5% tolerance and ±25ppm/°C TCR for critical analog/digital signal conditioning.
• Robust Power Handling: 0.75W total (0.1W per resistor) in a miniature 4.9mm x 6.02mm x 1.47mm footprint.
• Isolated Design (ISOL): Each resistor is electrically isolated, enabling flexible circuit configurations.
• Industrial-Grade Reliability: Thin film construction ensures long-term stability and low noise.
• Surface-Mount Optimized: QSOP package with 0.64mm terminal pitch for high-density PCB layouts.
• Non-Automotive/Non-PPAP: Ideal for industrial, telecom, and instrumentation applications.

GUS-QS8A-03-2493-DB Applications

• Precision Voltage Dividers: Used in ADC/DAC reference circuits and sensor interfaces.
• Medical Equipment: Stable resistance for patient monitoring and diagnostic devices.
• Test & Measurement: Calibration circuits and signal attenuation in lab instruments.
• Telecom Infrastructure: Impedance matching and filtering in RF/analog modules.
