GQ8A037501BT Description

The GQ8A037501BT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL) applications. Housed in a ceramic QSOP package, it offers a 7.5KΩ resistance per resistor with an exceptional 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The device features 16 gull-wing terminals with a 0.64mm pitch, making it suitable for surface-mount (SMD) PCB designs. Its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it robust for demanding circuits. Packaged in a tube, this non-automotive and non-PPAP compliant component is ideal for precision applications where isolation and reliability are critical.
