GQ0A0137R4JT

GQ0A0137R4JT Description

The GQ0A0137R4JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 37.4 Ω resistance, 5% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic package, it offers excellent thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The gull-wing termination ensures reliable surface-mount (SMD) connectivity, while the 0.64mm terminal pitch facilitates compact PCB layouts. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for demanding analog and mixed-signal circuits.
