GS7A011581JFT Description

The GS7A011581JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in a 14-pin narrow SOIC package, this 7-resistor isolated network features a 1.58KΩ resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%. Its thin-film technology ensures low noise and high reliability, while the ±100ppm/°C temperature coefficient guarantees consistent performance across a wide operating range of -70°C to +125°C. The SOIC-C series construction offers robust mechanical stability, with a compact footprint (8.66mm x 5.99mm x 1.45mm) and gull-wing terminations for easy surface-mount assembly.

GS7A011581JFT Features

• Isolated Circuit Design: Each of the 7 resistors is electrically isolated, enabling flexible circuit configurations.
• High Power Handling: 0.1W per resistor (0.7W total) with derating up to 125°C, ideal for power-sensitive designs.
• Precision Thin Film: Delivers low TCR (±100ppm/°C) and tight tolerance (±5%), ensuring accuracy in signal conditioning.
• Robust Packaging: Ceramic SOIC case provides excellent thermal dissipation and mechanical durability.
