GQ0A021272BBT Description

The GQ0A021272BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation (ISOL) applications. Encased in a robust 20-pin QSOP ceramic package, it integrates 10 isolated 12.7KΩ resistors with an exceptional ±0.1% tolerance and ±50ppm/°C temperature coefficient, ensuring stability across a wide temperature range (70°C to 125°C). With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount (SMD) component is ideal for precision analog circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while the ceramic case enhances thermal performance and durability.
