GQCA0278R7GGT Description

The GQCA0278R7GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package integrates 12 isolated resistors, each with a 78.7 Ω resistance value and a tight 2% tolerance. The ceramic case ensures excellent thermal stability, while the thin-film technology delivers low noise and high accuracy (±50 ppm/°C temperature coefficient). With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in demanding environments. Its gull-wing termination and surface-mount design facilitate easy PCB integration, making it ideal for compact, high-density layouts.

GQCA0278R7GGT Features

• Precision Performance: ±50 ppm/°C TCR and 2% tolerance ensure stable operation across a -70°C to +125°C temperature range.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• High-Density Integration: 12 resistors in a 6.02 x 8.66 mm QSOP package save board space.
• Isolated Design (ISOL): Each resistor is electrically isolated, reducing crosstalk in sensitive circuits.
• Surface-Mount Ready: Gull-wing leads with 0.64 mm pitch simplify automated assembly.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and telecom applications.
