GQ0A0228R0GCT Description

The GQ0A0228R0GCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a resistance value of 28Ω (±2% tolerance) and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a -70°C to +125°C temperature range. Encased in a ceramic package, it offers superior thermal conductivity and mechanical durability, making it suitable for demanding environments. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for circuits requiring isolation and consistent performance under varying loads.

GQ0A0228R0GCT Features
