GQ0A028661DBT Description

The GQ0A028661DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 8.66KΩ resistance value and an ultra-tight ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the 0.64mm terminal pitch facilitates high-density PCB layouts. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision signal conditioning and voltage division in critical circuits.

GQ0A028661DBT Features

• High Precision: ±0.5% tolerance and ±50ppm/°C TCR ensure stable performance across temperature fluctuations.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal dissipation and long-term reliability.
