GQCA017682DBT Description

The GQCA017682DBT by TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 76.8KΩ resistance and a tight ±0.5% tolerance, ensuring exceptional accuracy. The ceramic case style and thin-film technology provide superior stability, with a ±100ppm/°C temperature coefficient, making it ideal for environments with fluctuating thermal conditions. Rated for 1W total power dissipation (0.1W per resistor) and 100V maximum voltage, this surface-mount (SMD) component operates reliably across a 70°C to 125°C temperature range, with a 125°C maximum operating limit. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.

GQCA017682DBT Features

• Precision Performance: 0.5% tolerance and ±100ppm/°C TCR ensure minimal drift in critical circuits.
• Robust Construction: Ceramic substrate enhances thermal and mechanical durability.
• High-Density Design: 24-pin QSOP package (8.66mm × 6.02mm × 1.47mm) saves board space.
• Isolated Resistors: 12 independent resistors (ISOL circuit designator) prevent cross-talk in multi-channel systems.
• Wide Operating Range: -70°C to +125°C derated power range suits harsh environments.
• Surface-Mount Ready: Gull-wing leads and 0.64mm pitch simplify automated assembly.
