GQCA032742BT

GQCA032742BT Description

The GQCA032742BT 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 27.4KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case provides robust thermal and mechanical stability, while the gull-wing termination enables reliable surface-mount (SMD) assembly. With a ±25ppm/°C temperature coefficient and a 1W total power rating, this network maintains stable performance across a wide temperature range (70°C to 125°C derated). Packaged in a tube, it is suited for automated PCB production.

GQCA032742BT Features

• Precision Performance: 0.1% tolerance and ±25ppm/°C TCR ensure minimal drift in critical circuits.
• Robust Construction: Ceramic substrate enhances durability and heat dissipation.
• High-Density Design: 24-pin QSOP with 0.64mm pitch saves board space.
• Isolated Resistors: 12 independent 27.4KΩ resistors (100V max rating) for flexible circuit design.
• Wide Operating Range: -55°C to +125°C (full power up to 70°C).
