GQ0A0364R9DDT

GQ0A0364R9DDT Description

The GQ0A0364R9DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package features 10 isolated resistors, each with a 64.9Ω resistance and a tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case provides robust thermal and mechanical stability, while the gull-wing termination enables reliable surface-mount (SMD) assembly. With a ±25ppm/°C temperature coefficient, this network maintains stable performance across a wide temperature range (70°C to 125°C). Rated for 100V maximum voltage and 0.1W power dissipation per resistor (1W total), it is ideal for precision analog and digital systems.
