GQCA022940JFT Description

The GQCA022940JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and isolation between circuits. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 294Ω resistance, 5% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic package, it offers excellent thermal stability and durability, with a power rating of 0.1W per resistor (1W total). Its gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 100V maximum voltage rating and 125°C operating temperature make it suitable for demanding environments.

GQCA022940JFT Features

• High Isolation (ISOL): Independent resistors minimize crosstalk, ideal for signal integrity.
• Thin-Film Technology: Delivers superior precision, low noise, and stability vs. thick-film alternatives.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring reliability in thermal stress.
• Robust Construction: Ceramic case and gull-wing leads enhance mechanical and thermal endurance.
• Compact Footprint: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm length/height) suit space-constrained PCBs.
• Automotive-Grade Alternatives: While this model is not PPAP/automotive-certified, its performance parallels higher-tier options.
