GQCA0163R4DCT Description

The GQCA0163R4DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. Housed in a 24-pin QSOP package with a ceramic case, this 12-resistor array offers a 63.4Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±100ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates reliably across a -70°C to +125°C temperature range. The gull-wing termination and surface-mount design ensure compatibility with automated PCB assembly processes.

GQCA0163R4DCT Features

• Precision Thin Film Technology: Delivers stable performance with minimal drift over temperature and time.
• High-Density Isolation: 12 isolated resistors in a compact 8.66mm × 6.02mm × 1.47mm QSOP package, ideal for space-constrained designs.
• Robust Construction: Ceramic substrate enhances thermal stability and durability in harsh environments.
• Automation-Friendly: 0.64mm terminal pitch and gull-wing leads facilitate high-speed pick-and-place assembly.
• Wide Operating Range: Derated power capability up to 125°C suits industrial and telecom applications.
• Non-Automotive Grade: Optimized for commercial/industrial use (PPAP not required).
