GQ8A021780DCT Description

The GQ8A021780DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 178Ω resistance value with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for high-density circuits requiring reliable power dissipation. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in high-voltage environments.

GQ8A021780DCT Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±50ppm/°C) for stable operation.
• Robust Ceramic Package: Ensures thermal stability and mechanical strength in harsh conditions.
• High Power Handling: 0.75W total rating (0.1W per resistor) supports power-sensitive applications.
• Isolated Circuit Design (ISOL): Independent resistors minimize crosstalk, ideal for signal integrity.
• Compact QSOP-16 Form Factor: 4.9mm × 6.02mm × 1.47mm dimensions with ±0.1mm tolerances enable space-efficient layouts.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
