GQ8A0143R2GGT Description

The GQ8A0143R2GGT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic QSOP package, this 16-pin SMD component offers a 43.2Ω resistance per resistor with a tight 2% tolerance and a ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Its isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for complex circuit configurations. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it balances power handling and compactness (4.9mm x 6.02mm x 1.47mm). The gull-wing termination ensures reliable surface-mount assembly, while the ceramic case enhances thermal and mechanical durability.
