GQ8A0139R0FCT Description

The GQ8A0139R0FCT from TT Electronics/IRC is a high-performance, surface-mount thin-film resistor network designed for precision applications. This 8-resistor array features a 39Ω resistance value per resistor with a tight tolerance of ±1% and a low temperature coefficient of ±100ppm/°C, 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 superior thermal stability and durability, making it ideal for demanding environments. The network is configured in an isolated (ISOL) circuit design, providing independent resistors for flexible circuit integration. 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).
