GQCA034120CBT

GQCA034120CBT Description

The GQCA034120CBT 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 412 Ω resistance value and an exceptional ±0.25% tolerance, ensuring reliable signal conditioning and voltage division in precision circuits. The ceramic case style and gull-wing termination provide robust mechanical stability and ease of surface-mount (SMD) assembly. With a ±25 ppm/°C temperature coefficient, this network maintains stable performance across a wide operating range of 70°C to 125°C, making it suitable for environments with thermal fluctuations.

GQCA034120CBT Features

• Precision Performance: 0.25% tolerance and ±25 ppm/°C TCR ensure minimal drift in critical applications.
• High Power Handling: 1W total power rating (0.1W per resistor) supports distributed load requirements.
• Robust Construction: Ceramic substrate enhances thermal dissipation and durability.
• Isolated Design: 12 independent resistors (ISOL circuit designator) enable flexible circuit configurations.
• Surface-Mount Ready: QSOP package with 0.64mm pitch and gull-wing leads for automated PCB assembly.
• Wide Voltage Range: 100V maximum rating accommodates diverse signal and power applications.

GQCA034120CBT Applications

This resistor network excels in:
