GQCA034991DBT Description

The GQCA034991DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP device features 12 isolated resistors, each with a 4.99KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy. The ceramic case and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a ±25ppm/°C temperature coefficient, it maintains stable performance across a wide operating range of 70°C to 125°C, derated for optimal power handling. Rated at 1W total power (0.1W per resistor) and 100V maximum voltage, it suits precision analog and digital circuits. Packaged in a tube, this non-automotive, non-PPAP component is ideal for prototyping and low-to-medium volume production.
