GQ8A037502BT Description

The GQ8A037502BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 75kΩ resistance value per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate compact PCB integration, while the isolated (ISOL) circuit configuration enhances signal integrity in multi-channel systems.
