GUS-QS8A-01-5491-JB Description

The GUS-QS8A-01-5491-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 5.49KΩ resistance value per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Packaged in a 16-pin QSOP with gull-wing terminations, it offers a compact 4.9mm x 6.02mm footprint and a low-profile 1.47mm height, making it ideal for space-constrained surface-mount (SMD) designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling and miniaturization.

GUS-QS8A-01-5491-JB Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and stability compared to thick-film alternatives.
• Isolated Design (ISOL): Each resistor operates independently, enhancing flexibility in circuit design.
• High Power Density: 0.1W per resistor (0.75W total) in a compact QSOP package, ideal for densely populated PCBs.
• Wide Temperature Range: Reliable operation from -55°C to +125°C (derated above 70°C).
• Robust Construction: Gull-wing terminals ensure secure soldering, while ±0.1mm length/height tolerances aid precision placement.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance isn’t required.
