GQCB011871FBT Description

The GQCB011871FBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 1.87K Ohm resistance value with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Encased in a ceramic QSOP package, it offers excellent thermal stability and durability. The 24-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.05W (1/20) power rating per resistor and 1W total power rating make it suitable for demanding circuits. With a maximum voltage rating of 100V, this network is ideal for bus termination, pull-up/pull-down, and voltage division in high-reliability systems.
