GQ0A0245R3JCT Description

The GQ0A0245R3JCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 45.3 Ω resistance, 5% tolerance, and a ±50ppm/°C temperature coefficient. The ceramic case ensures excellent thermal stability, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network operates reliably across a wide temperature range of 70°C to 125°C. Packaged in a tube, it is ideal for automated PCB assembly.

GQ0A0245R3JCT Features

• High Precision: Thin-film technology ensures low noise and stable performance.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• Isolated Resistors: 10 independent resistors (ISOL designator) prevent crosstalk in sensitive circuits.
• Wide Operating Range: Suitable for harsh environments (-70°C to +125°C derated).
• Space-Efficient: Compact QSOP package (8.66mm × 6.02mm × 1.47mm) with 0.64mm pitch for high-density layouts.
• Automation-Friendly: Gull-wing leads and tube packaging streamline SMD processes.

GQ0A0245R3JCT Applications
