GUS-QS8A-03-1020-JC Description

The GUS-QS8A-03-1020-JC is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and low-temperature coefficients. This 8-resistor isolated network features a 102Ω resistance per element with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -55°C to +125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and a 0.64mm terminal pitch, making it ideal for high-density PCB designs. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network excels in demanding environments.

GUS-QS8A-03-1020-JC Features

• Thin-film technology: Delivers superior stability, low noise, and precise resistance matching.
• Isolated design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• High power handling: 0.75W total power dissipation (3/4W) with derating up to 125°C.
• Robust construction: QSOP package with gull-wing leads ensures mechanical durability and ease of soldering.
• Wide temperature range: Operates from -55°C to +125°C, suitable for industrial and automotive (non-AEC-Q200) applications.
• Non-RoHS compliant: Ideal for legacy systems or applications exempt from RoHS restrictions.
