GQ8A038450CT Description

The GQ8A038450CT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it offers 845Ω resistance per element with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical robustness.

GQ8A038450CT Features

• Precision Performance: Ultra-tight tolerance (±0.25%) and low TCR (±25ppm/°C) for critical analog/digital systems.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) derated up to 125°C.
• Isolated Design (ISOL): Independent resistors minimize crosstalk in multi-channel applications.
• Robust Construction: Ceramic substrate and gull-wing leads ensure durability in harsh environments.
• Compact Footprint: 4.9mm × 6.02mm × 1.47mm QSOP package with ±0.1mm dimensional tolerances for space-constrained PCBs.
