GQ0A011052JT

GQ0A011052JT Description

The GQ0A011052JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 10-resistor array features a 10.5KΩ resistance per element with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring consistent 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, with a 1W total power rating (0.1W per resistor). The 20-pin gull-wing SMD termination ensures secure surface mounting, while the 100V maximum voltage rating makes it suitable for moderate-voltage circuits.
