GUS-QS8A-02-3921-CA Description

The GUS-QS8A-02-3921-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount (SMD) applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 3.92KΩ resistance, offering a tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C (derated) and up to 125°C maximum. Its gull-wing termination and 0.64mm terminal pitch ensure secure PCB mounting, while the compact 4.9mm x 6.02mm x 1.47mm footprint suits space-constrained designs.

GUS-QS8A-02-3921-CA Features

• Precision Performance: Thin-film technology delivers 0.25% tolerance and ±50ppm/°C stability, ideal for signal conditioning and analog circuits.
• Robust Construction: 100V maximum voltage rating and isolated (ISOL) circuit design enhance reliability in high-voltage or noise-sensitive environments.
• Thermal Efficiency: Derated power handling up to 125°C ensures consistent operation in elevated temperatures.
• Compact & Durable: QSOP package with 1.63mm seated height and rectangular shape optimizes board space while resisting mechanical stress.
