GQ8A021501CBT Description

The GQ8A021501CBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it features 1.5KΩ resistors with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. The isolated (ISOL) circuit design provides independent resistor paths, making it ideal for applications requiring electrical separation. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network balances precision with robustness. Its gull-wing SMD termination and compact 4.9mm × 6.02mm × 1.47mm footprint suit space-constrained PCB layouts.
