GQCA039762DBT Description

The GQCA039762DBT 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 97.6KΩ resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The device operates over a wide temperature range of 70°C to 125°C with a ±25ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. Encased in a ceramic package, it offers superior thermal stability and durability, while its gull-wing termination ensures reliable surface-mount (SMD) assembly. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for precision analog and mixed-signal systems.

GQCA039762DBT Features

• High Precision: 0.5% tolerance and ±25ppm/°C TCR for stable performance in precision circuits.
• Robust Construction: Ceramic case style enhances thermal management and mechanical strength.
• Isolated Resistors: 12 independent resistors (ISOL circuit design) prevent crosstalk in multi-channel designs.
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch for compatibility with automated PCB assembly.
• Wide Operating Range: -70°C to +125°C derated power range, ideal for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Compact Footprint: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm length/height, ±0.2mm depth) for space-constrained layouts.
