GQCB0256R0GDT Description

The GQCB0256R0GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package integrates 23 resistors, each with a 56Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. Built with ceramic substrate and gull-wing termination, it offers excellent thermal stability and reliable surface-mount compatibility. The network operates across a wide temperature range (-70°C to +125°C) with a low ±50ppm/°C temperature coefficient, making it suitable for environments with fluctuating thermal conditions. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it balances power handling with compact dimensions (8.66mm x 6.02mm x 1.47mm).
