GUS-QS8A-01-4531-JA Description

The GUS-QS8A-01-4531-JA from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a compact 16-pin QSOP package with gull wing termination, this surface-mount device offers a 4.53KΩ resistance per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient. Its isolated circuit design (ISOL) ensures independent resistor functionality, while the 0.75W (3/4W) total power rating and 0.1W per resistor capability make it suitable for demanding environments. Operating within a -70°C to +125°C temperature range, it excels in stability under thermal stress, with a maximum voltage rating of 100V. The QSOP package (4.9mm x 6.02mm x 1.47mm) ensures space efficiency, ideal for densely populated PCBs.

GUS-QS8A-01-4531-JA Features

• Thin Film Technology: Delivers superior accuracy, low noise, and stable performance over time compared to thick-film alternatives.
• High Power Handling: 0.75W total power dissipation (0.1W per resistor) enables robust operation in power-sensitive circuits.
• Wide Temperature Range: Reliable performance from -70°C to +125°C, with derated power handling up to 125°C.
• Isolated Design (ISOL): Each resistor operates independently, reducing cross-talk and improving signal integrity.
• Compact QSOP Package: 16-pin gull-wing SMD with 0.64mm terminal pitch optimizes board space without sacrificing thermal performance.
