GUS-QS8A-02-35R7-JC Description

The GUS-QS8A-02-35R7-JC from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision surface-mount applications. This thin-film resistor array offers a 35.7Ω resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP package, it features gull-wing terminations for reliable SMD assembly and a 0.64mm terminal pitch for high-density PCB layouts. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for demanding industrial and commercial circuits.

GUS-QS8A-02-35R7-JC Features

• Isolated Design (ISOL): Each resistor operates independently, eliminating crosstalk for critical signal integrity.
• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) supports energy-intensive applications.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated performance up to 125°C.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint saves board space in dense designs.
• Gull-Wing Termination: Ensures robust solder joints and compatibility with automated pick-and-place processes.

GUS-QS8A-02-35R7-JC Applications

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to low TCR (±50ppm/°C) and tight tolerance.
• Industrial Control Systems: Isolated resistors prevent signal interference in PLCs and sensor interfaces.
• Medical Electronics: Stable performance suits patient monitoring equipment and diagnostic devices.
• Telecommunications: Used in RF matching networks and line termination for impedance control.
• Automotive (Non-Automotive Rated): Suitable for infotainment or climate control systems where PPAP compliance isn’t required.
