GQCA031433CBT Description

The GQCA031433CBT 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 143KΩ resistance value and an ultra-tight ±0.25% tolerance. Encased in a ceramic package, it ensures superior thermal stability and durability, operating across a wide temperature range of 70°C to 125°C with a derated power profile. The 1W total power rating (0.1W per resistor) and ±25ppm/°C temperature coefficient make it ideal for precision analog circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the 100V maximum voltage rating ensures reliability in high-voltage environments.

GQCA031433CBT Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR for stable performance in critical applications.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal and mechanical resilience.
• Isolated Design: 12 resistors with independent isolation (ISOL circuit designator) minimize crosstalk.
• Compact Form Factor: 8.66mm × 6.02mm × 1.47mm QSOP package with 0.64mm pitch for high-density PCB layouts.
• Wide Operating Range: Supports -55°C to 125°C (full power up to 70°C) for industrial and automotive-grade reliability.
• Surface-Mount Ready: Gull-wing terminals and tube packaging streamline pick-and-place processes.
