GUS-QS8A-01-1403-JA Description

The GUS-QS8A-01-1403-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 8 isolated resistors, each with a 140K Ohm resistance, 5% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, this network is optimized for compact, high-density circuits requiring reliable power dissipation. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and automated placement, while the 1.47mm low-profile height makes it suitable for space-constrained designs.

GUS-QS8A-01-1403-JA Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, enhancing design flexibility in multi-channel circuits.
• High Power Handling: 0.75W total rating (0.1W per resistor) ensures reliability in power-sensitive applications.
