GQCA027872GFT Description

The GQCA027872GFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP package integrates 12 isolated resistors, each with a 78.7KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in precision circuits. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees stability across a wide operating range of -70°C to +125°C. With a maximum voltage rating of 100V and a 1W total power dissipation, this network is engineered for reliability in compact, high-density PCB layouts.

GQCA027872GFT Features

• High Isolation (ISOL) Design: Ideal for circuits requiring signal separation or noise immunity.
• Thin-Film Technology: Delivers superior accuracy (±2%) and low TCR (±50ppm/°C) compared to thick-film alternatives.
• Robust Construction: Ceramic substrate enhances thermal and mechanical durability.
• Space-Efficient QSOP Package: Measures just 8.66mm x 6.02mm x 1.47mm, optimizing board real estate.
• Gull-Wing Termination: Facilitates reliable soldering and automated assembly processes.
• Derated Power Handling: Maintains performance up to 125°C with derated power (0.1W per resistor).
