GS7A018201JFT Description

The GS7A018201JFT from TT Electronics/IRC is a high-performance 7-resistor isolated network in a 14-pin narrow SOIC package. Designed with thin-film technology on a ceramic substrate, it offers excellent stability and precision with a ±100ppm/°C temperature coefficient and ±5% absolute tolerance. Each resistor features an 8.2KΩ resistance value and a 0.1W (1/10) power rating per element, totaling 0.7W for the entire network. The device operates within a wide temperature range of 70°C to 125°C (derated) and withstands up to 125°C maximum operating temperature. Its 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount applications requiring reliable isolation and compact design.

GS7A018201JFT Features

• Isolated Circuit Design: Ensures independent resistor performance, ideal for precision applications.
• Ceramic SOIC Package: Provides superior thermal and mechanical stability compared to polymer-based networks.
• Low TCR (±100ppm/°C): Maintains stable resistance across temperature variations.
• High Power Handling: 0.7W total dissipation (0.1W per resistor) supports demanding circuits.
• Tight Ratio Tolerance (±1%): Critical for differential amplifiers, voltage dividers, and sensor interfaces.
• Robust Construction: Rectangular SOIC-C case with ±0.1mm height/length tolerances ensures consistent PCB mounting.
