Low Frequency Flexible Ferrite Sheet: FFS Series
High performance noise suppression ferrite sheet, targets low frequency noise around 1MHz
- Thin (0.3mm thick) ferrite sheet with higher loss
- Sintered ferrite, but intentionally cracked for flexibility and sandwiched between an adhesive layer and mylar to hold the material together
- Achieves excellent performance in suppression noise by simply attaching FFS to desired areas
- No fixture is necessary, adhesive on one side for easy mounting onto chip
- RoHS Compliant
