GUS-QS8A-02-5102-JA Description

The GUS-QS8A-02-5102-JA from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount circuits. Encased in a 16-pin QSOP package with gull-wing terminations, this device offers a 51KΩ resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Its isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for complex signal conditioning and impedance matching. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this network balances compact dimensions (4.9mm × 6.02mm × 1.47mm) with robust power handling.

GUS-QS8A-02-5102-JA Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• High Power Density: 0.1W per resistor (total 0.75W) in a miniature QSOP package, optimizing board space.
• Wide Operating Range: Reliable performance from -55°C to +125°C, derated up to 125°C.
• Isolated Configuration: Each of the 8 resistors operates independently, enhancing design flexibility.
• Automated Assembly-Friendly: Gull-wing leads and 0.64mm pitch ensure compatibility with high-speed SMT processes.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance isn’t required.
