GQCB012491JDT Description

The GQCB012491JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 2.49KΩ resistance value per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a 24-pin QSOP (Ceramic) package, it offers a compact rectangular footprint (8.66mm x 6.02mm x 1.47mm) with gull-wing SMD terminations for reliable surface mounting. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it is ideal for high-density PCB designs requiring consistent signal integrity.
