GQ0A031742FBT Description

The GQ0A031742FBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package features 10 isolated resistors, each with a 17.4KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and thermal stability, making it suitable for surface-mount (SMD) applications. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits.

GQ0A031742FBT Features

• High Precision: 1% tolerance and ±25ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic substrate enhances thermal dissipation and durability.
• Isolated Resistors: 10 independent resistors in a single package, reducing board space and improving signal integrity.
• Surface-Mount Design: QSOP-20 gull-wing terminals for reliable SMT assembly.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Low Noise: Thin-film technology minimizes parasitic effects, ideal for sensitive analog circuits.

GQ0A031742FBT Applications
