GQ8A0251R0JGT Description

The GQ8A0251R0JGT from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications. Built with thin-film technology on a ceramic substrate, it delivers a 51Ω resistance per element with a 5% tolerance and ±50ppm/°C temperature coefficient. Encased in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained designs. Rated for 0.75W total power (0.1W per resistor) and 100V maximum voltage, it operates reliably across a -70°C to +125°C temperature range. The isolated circuit design (ISOL) ensures minimal crosstalk, while the ceramic case enhances thermal stability and durability.

GQ8A0251R0JGT Features

• Precision Thin Film: Low TCR (±50ppm/°C) and tight tolerance (±5%) for stable performance.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) in a compact QSOP package.
• Isolated Network (ISOL): Independent resistors reduce interference in sensitive circuits.
• Robust Construction: Ceramic substrate and gull-wing terminals ensure mechanical and thermal resilience.
• Wide Operating Range: -70°C to +125°C, suitable for industrial and automotive environments (non-AECQ).
• Surface-Mount Ready: 0.64mm pitch for automated PCB assembly.
