GQ0A021741BBT Description

The GQ0A021741BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a resistance value of 1.74 kΩ and an ultra-tight tolerance of ±0.1%, ensuring exceptional accuracy in circuit performance. The ceramic case style and gull-wing termination enable reliable surface-mount assembly, while the ±50 ppm/°C temperature coefficient guarantees stability across a wide operating range of 70°C to 125°C. With a 100V maximum voltage rating and 0.1W power rating per resistor (1W total), this network is engineered for precision analog and digital systems requiring minimal drift and high isolation.

GQ0A021741BBT Features

• High Precision: ±0.1% tolerance and ±50 ppm/°C TCR for stable performance in temperature-variable environments.
• Robust Construction: Ceramic substrate and thin-film technology enhance durability and thermal dissipation.
• Compact Design: QSOP package (8.66mm × 6.02mm × 1.47mm) with 0.64mm pitch, ideal for space-constrained PCBs.
