GQCA011273GGT Description

The GQCA011273GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Encased in a ceramic QSOP package, this 24-pin SMD component integrates 12 isolated resistors, each rated at 127KΩ with a tight 2% tolerance and ±100ppm/°C temperature coefficient. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C, making it suitable for demanding environments. The gull-wing termination ensures secure surface mounting, while the ceramic case enhances durability and heat dissipation.
