GQ0A011152CT Description

The GQ0A011152CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. This 20-pin QSOP surface-mount device integrates 10 isolated resistors, each with a 11.5KΩ resistance and a tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Encased in a ceramic package, it offers superior thermal stability and mechanical robustness, with a wide operating temperature range of 70°C to 125°C (derated) and a maximum rating of 125°C. Its ±100ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for precision analog and mixed-signal systems.
