GS7A015490JFT Description

The GS7A015490JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 14-pin narrow SOIC package features 7 isolated thin-film resistors, each with a 549Ω resistance and a ±5% absolute tolerance. The device operates within a wide temperature range of -70°C to +125°C, with a ±100ppm/°C temperature coefficient, ensuring minimal drift under varying environmental conditions. Its 0.1W power rating per resistor (0.7W total) and 100V maximum voltage rating make it suitable for demanding circuits. The SOIC-C series construction offers a compact footprint (8.66mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly.

GS7A015490JFT Features

• Isolated Circuit Design: Each of the 7 resistors is electrically isolated, enabling flexible circuit configurations.
• High Stability: Thin-film technology and ceramic case ensure low noise and excellent thermal dissipation.
• Precision Tolerance: ±5% absolute tolerance and ±1% ratio tolerance for matched resistance values.
• Robust Construction: SOIC package with rectangular ceramic body resists mechanical stress and thermal cycling.
• Wide Operating Range: -70°C to +125°C derated power capability, ideal for harsh environments.
• Surface-Mount Ready: 1.27mm terminal pitch and gull-wing leads simplify PCB integration.
