GQ0A0351R1DDT Description

The GQ0A0351R1DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 51.1 Ω resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in voltage division and impedance matching. The ceramic case and gull-wing SMT termination provide robust mechanical stability and reliable solderability, while the ±25 ppm/°C temperature coefficient guarantees minimal drift across operating temperatures of 70°C to 125°C. With a 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor), this network is ideal for precision analog and mixed-signal designs.
