GQ0A0169R8DCT

GQ0A0169R8DCT Description

The GQ0A0169R8DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 69.8Ω resistance, 0.5% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The ceramic case and gull-wing termination provide robust mechanical and thermal stability, while the 1W total power rating (0.1W per resistor) supports moderate power dissipation. With a 100V maximum voltage rating and surface-mount (SMD) design, this network is ideal for compact, high-reliability circuits.

GQ0A0169R8DCT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital systems.
• Isolated Resistor Network (ISOL): 10 independent resistors prevent crosstalk, ideal for isolation barriers.
• High Power Density: 1W total dissipation (0.1W per resistor) in a compact 8.66mm × 6.02mm × 1.47mm footprint.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Robust Construction: Ceramic substrate and gull-wing leads ensure durability in harsh environments.
• QSOP Package: 0.64mm terminal pitch enables high-density PCB layouts.
