GUS-QS8A-03-1201-CA Description

The GUS-QS8A-03-1201-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated 1.2KΩ resistors with an exceptional tolerance of ±0.25% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. With a maximum voltage rating of 100V and a total power rating of 0.75W (3/4W), it delivers reliable power dissipation in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while its rectangular, tube-packaged form factor (4.9mm x 6.02mm x 1.47mm) optimizes board space efficiency.

GUS-QS8A-03-1201-CA Features
