GQ8A021270JCT Description

The GQ8A021270JCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 127Ω resistance value with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design make it ideal for automated assembly processes. The ceramic case provides excellent thermal and mechanical stability, while the isolated circuit design (ISOL) ensures minimal crosstalk between resistors.

GQ8A021270JCT Features

• High Precision: Thin-film technology delivers low TCR (±50ppm/°C) and tight tolerance (5%) for reliable performance.
• Robust Construction: Ceramic package ensures durability and thermal efficiency, with a seated height of 1.63mm and compact 4.9mm × 6.02mm footprint.
• Isolated Design: 8 independent resistors (ISOL configuration) reduce interference in sensitive circuits.
• Wide Operating Range: Suitable for -55°C to +125°C environments, with derated power up to 125°C.
• Automation-Friendly: Gull-wing leads and 0.64mm pitch enable seamless SMD placement.
• Non-Automotive: Compliant with EAR99 (ECCN) but not PPAP or RoHS certified.
