GQ0A012102CAT Description

The GQ0A012102CAT 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 21kΩ resistance value and an exceptional ±0.25% tolerance. Encased in a ceramic package, it offers superior thermal stability and reliability, with a ±100ppm/°C temperature coefficient and a maximum operating temperature of 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.

GQ0A012102CAT Features

• High Precision: Tight tolerance (±0.25%) and low TCR (±100ppm/°C) ensure stable performance in temperature-varying environments.
• Robust Construction: Ceramic case provides excellent thermal dissipation and mechanical durability.
• Isolated Resistors: 10 independent resistors (ISOL circuit designator) allow flexible circuit configurations.
• Surface-Mount Design: Gull-wing termination and 0.64mm terminal pitch enable compact PCB layouts.
• Wide Temperature Range: Operates reliably from 70°C to 125°C at derated power.
• Non-Automotive, Non-PPAP: Ideal for industrial and commercial applications where automotive-grade certification is not required.
