GQCA023922JFT Description

The GQCA023922JFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit isolation and signal conditioning applications. This 24-pin QSOP surface-mount device integrates 12 isolated resistors, each with a 39.2KΩ resistance (5% tolerance) and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic package, it offers superior thermal stability and durability, with a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GQCA023922JFT Features

• Isolated Resistor Network: 12 resistors with independent isolation (ISOL designator), reducing crosstalk in precision circuits.
• Thin-Film Technology: Delivers low noise, high accuracy (±5%), and excellent long-term stability.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical strength for harsh environments.
• Wide Operating Range: Rated for -55°C to +125°C (derated power up to 125°C), ideal for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Compact QSOP Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length) for high-density layouts.
