GQCA019311CBT Description

The GQCA019311CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP (Quarter-Small Outline Package) device integrates 12 isolated resistors, each with a 9.31KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in circuit matching. Encased in a ceramic package, it offers superior thermal stability and reliability across a wide temperature range of -70°C to +125°C. The gull-wing termination and surface-mount design facilitate automated assembly, while the 1W total power rating (0.1W per resistor) supports robust performance in compact layouts.

GQCA019311CBT Features

• Precision Thin Film Technology: Delivers ±100ppm/°C temperature coefficient for minimal drift in varying environments.
• High Voltage Isolation: 100V maximum rating per resistor, ideal for signal isolation in mixed-voltage systems.
• Compact & Robust: 8.66mm x 6.02mm x 1.47mm dimensions with ±0.1mm length/height tolerances ensure consistent PCB fit.
• Ceramic Case: Enhances thermal dissipation and mechanical durability compared to plastic alternatives.
