GQ0A034320DBT Description

The GQ0A034320DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP package features 10 isolated resistors, each with a 432 Ω resistance value and an exceptional ±0.5% tolerance, ensuring consistent performance in precision circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±25ppm/°C temperature coefficient ensures stability across a wide operating range of -70°C to +125°C. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, this network is ideal for high-density PCB designs requiring tight electrical and thermal performance.
