GQ0A019100CAT Description

The GQ0A019100CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 910Ω resistance, 0.25% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic package, it offers excellent thermal stability and reliability, with a maximum operating temperature of 125°C and a derated power range of 70–125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GQ0A019100CAT Features

• High Precision: Tight 0.25% tolerance and ±100ppm/°C TCR ensure stable performance in temperature-varying environments.
• Robust Construction: Ceramic case and thin-film technology provide superior durability and low noise.
• Space-Efficient Design: Compact QSOP package (8.66mm × 6.02mm × 1.47mm) with gull-wing SMD termination for easy PCB integration.
• Isolated Resistors: 10 independent resistors (ISOL circuit designator) enable flexible circuit design without crosstalk.
• Wide Operating Range: Supports -55°C to +125°C with derated power up to 125°C, ideal for industrial and automotive-grade applications (though not PPAP/automotive-certified).
