GQCB012872DCT Description

The GQCB012872DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 23-resistor array features a 28.7KΩ resistance value per resistor with a 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 24-pin QSOP ceramic package, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.
