GQ0A037870GT Description

The GQ0A037870GT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 10-resistor array features a 787Ω resistance value with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers 1W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The 20-pin gull-wing SMD termination ensures secure surface mounting, while the isolated (ISOL) circuit design provides enhanced signal integrity in multi-channel systems.
