GQ0A0228R7FDT Description

The GQ0A0228R7FDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a resistance value of 28.7Ω and a tight tolerance of ±1%. The ceramic case ensures excellent thermal stability, while the gull-wing termination style facilitates reliable surface-mount assembly. With a power rating of 1W (0.1W per resistor) and a maximum operating temperature of 125°C, this network is engineered for demanding environments. Its ±50ppm/°C temperature coefficient guarantees minimal resistance drift over a wide temperature range (70°C to 125°C). The 100V maximum voltage rating and isolated (ISOL) circuit design make it suitable for high-voltage applications requiring electrical separation between channels.
