GQCA0253R6CCT

GQCA0253R6CCT Description

The GQCA0253R6CCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 53.6 Ω resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in circuit matching. The ceramic case provides robust thermal and mechanical stability, while the gull-wing termination enables reliable surface-mount assembly. With a ±50ppm/°C temperature coefficient and a 100V maximum voltage rating, this network delivers stable performance across a 70°C to 125°C operating range, making it suitable for precision analog and digital systems.

GQCA0253R6CCT Features

• High Precision: 0.25% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• Isolated Design: 12 resistors with independent isolation (ISOL) reduce crosstalk in multi-channel systems.
• Power Handling: 0.1W per resistor (1W total) supports moderate power dissipation.
• Compact Form Factor: 8.66mm × 6.02mm × 1.47mm QSOP package optimizes board space.
• Surface-Mount Ready: Gull-wing leads with 0.64mm pitch simplify automated assembly.
