GUS-QS8A-03-8201-CA Description

The GUS-QS8A-03-8201-CA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a resistance value of 8.2KΩ and an ultra-tight tolerance of ±0.25%, this component ensures exceptional accuracy in signal conditioning, voltage division, and impedance matching circuits. Housed in a compact 16-pin QSOP (QSOP-16) package, it features gull-wing terminations for reliable solderability and mechanical stability. The device operates across a wide temperature range of -70°C to +125°C, making it suitable for industrial and instrumentation environments. Its low TCR of ±25ppm/°C minimizes resistance drift under thermal stress, while the isolated (ISOL) circuit design allows flexible configuration in complex PCB layouts.

GUS-QS8A-03-8201-CA Features

• Precision Performance: Thin film technology delivers 0.25% tolerance and ±25ppm/°C TCR for stable operation in fluctuating temperatures.
• Robust Power Handling: 0.1W per resistor (total 0.75W for the network) ensures reliability in power-sensitive designs.
• Compact Form Factor: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with a 0.64mm terminal pitch, ideal for high-density PCBs.
• High Voltage Rating: Supports up to 100V, suitable for industrial control systems and test equipment.
• Isolated Design: Independent resistors (ISOL) enable versatile circuit integration without shared node limitations.
• Surface-Mount Ready: Gull-wing leads comply with automated assembly processes, reducing manufacturing costs.
