FST-F - FOIL SCREENED STRANDED CONDUCTOR TWIN CABLE Flexible
This D'n'A series (Digital and Analogue) cable is designed to be suitable for both digital and analogue audio signals, with an impedance of 100 ohms which has been proven to be suitable for AES/EBU digital audio as well as analogue microphone and line level signals. Wire insulation is polypropylene, which shrinks back minimally during soldering (considerably less than PVC or polyethylene).
This cable is constructed in a similar way to the easy-strip FST, but has changes to improve the flexibility, which may be desired in some applications. The insulation has a slightly reduced wall thickness, and a significantly longer lay length of the twist than FST, giving a single, long length strip. The overall jacket is a soft PVC with semi-matt finish, and overall diameter is slightly less the FST. Conductor sizes are the same in both FST and FST-F.
