GQCA0275R0GGT

GQCA0275R0GGT Description

The GQCA0275R0GGT 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 75Ω resistors with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and thermal stability, making it suitable for surface-mount (SMD) assembly in compact PCB designs. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network excels in precision analog and digital circuits.

GQCA0275R0GGT Features

• High Isolation: Designed for ISOL (isolation) applications, minimizing crosstalk between channels.
• Thin-Film Technology: Delivers superior accuracy (±2%) and low TCR (±50ppm/°C) compared to thick-film alternatives.
• Robust Construction: Ceramic substrate ensures high thermal conductivity and durability in harsh environments.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch for high-density layouts.
• Derated Power Handling: Maintains performance up to 125°C with derated power capabilities.
• Non-Automotive: Ideal for industrial and telecom applications where PPAP compliance is not required.
