GQ0A021801FT Description

The GQ0A021801FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package features 10 isolated 1.8KΩ resistors with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination make it ideal for surface-mount (SMD) applications, while its 0.1W (1/10) power rating per resistor and 1W total power rating provide reliable operation in compact designs. With a maximum voltage rating of 100V, this network is suited for precision analog and digital circuits.

GQ0A021801FT Features

• High Precision: 1% tolerance and ±50ppm/°C TCR for consistent performance.
• Robust Construction: Ceramic substrate ensures durability and thermal stability.
• Compact Design: 8.66mm × 6.02mm × 1.47mm dimensions with 0.64mm terminal pitch for high-density PCB layouts.
• Isolated Resistors: 10 independent resistors (ISOL configuration) for flexible circuit design.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Surface-Mount Ready: Gull-wing terminals for reliable SMD assembly.
