GQ8A0147R5DCT Description

The GQ8A0147R5DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 47.5Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing SMD termination and 0.64mm terminal pitch facilitate easy surface mounting in space-constrained designs.
