GQ0A0161R9CCT Description

The GQ0A0161R9CCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation circuit applications. This 20-pin QSOP surface-mount device integrates 10 isolated resistors, each with a 61.9 Ω resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division. Encased in a robust ceramic package, it offers superior thermal stability across a wide temperature range (70°C to 125°C) and a ±100ppm/°C TCR, minimizing drift in harsh environments. With a 100V maximum voltage rating and 0.1W power dissipation per resistor (1W total), it balances compactness (8.66mm × 6.02mm × 1.47mm) with reliability.
