GQCA021740DCT

GQCA021740DCT Description

The GQCA021740DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated resistors, each with a 174 Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±50 ppm/°C temperature coefficient guarantees stable performance across a wide operating range of 70°C to 125°C. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for precision analog and digital systems.

GQCA021740DCT Features

• High Precision: 0.5% tolerance and ±50 ppm/°C TCR for minimal drift in critical circuits.
• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Isolated Resistors: 12 independent resistors (ISOL design) prevent crosstalk in multi-channel applications.
• Space-Efficient: Compact QSOP package (8.66 x 6.02 x 1.47 mm) with 0.64 mm pitch for high-density PCB layouts.
• Reliable Performance: 125°C maximum operating temperature and 1W total power dissipation suit industrial environments.
• Non-Automotive: Not PPAP-capable, ideal for industrial, medical, and test/measurement equipment.
