GQ0A026981FT Description

The GQ0A026981FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 6.98KΩ resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers superior thermal stability and durability. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C temperature range. The gull-wing termination and surface-mount design ensure easy integration into compact PCB layouts.

GQ0A026981FT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistor Network (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Ceramic Case: Enhances thermal dissipation and mechanical robustness.
• Wide Temperature Range: Maintains performance from -55°C to 125°C (derated power up to 125°C).
• Compact QSOP Package: 8.66mm x 6.02mm x 1.47mm dimensions with ±0.1mm length/height tolerances for high-density designs.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its reliability suits industrial and telecom applications.
