GQ0A033321CT Description

The GQ0A033321CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 3.32KΩ resistance, a tight ±0.25% tolerance, and a low ±25ppm/°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). The gull-wing termination ensures reliable surface-mount (SMD) assembly, while its 100V maximum voltage rating and 125°C operating range make it suitable for harsh environments.

GQ0A033321CT Features

• Precision Performance: Thin-film technology delivers ±0.25% tolerance and ±25ppm/°C TCR for stable, accurate signal processing.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength, ideal for high-reliability systems.
• Isolated Design: 10 resistors with independent paths (ISOL circuit designator) prevent crosstalk in sensitive circuits.
• Compact & Durable: QSOP package (8.66mm × 6.02mm × 1.47mm) with ±0.1mm dimensional tolerances ensures consistent PCB fit.
• Wide Operating Range: Functions from 70°C to 125°C with derated power, exceeding standard industrial requirements.
