Ordered these at HK recommendation for missing cores from switching regulator I purchased from HK. They had reimbursed me for the switch which paid for shipping and the new cores. Thanks HK.

i got these ferrite rings for diy lc filters for my fpv system. if you want to do a real good job, use one of the online calculators to calculate how many windings you need. really easy to use. add a capacitor for extra smooth filtering. real cheap and high quality filter. make sure to be aware of the size and weight the filter will have. for real small currents (< 1 A) you can actually get ready-made lc filters which are a fair bit smaller and lighter, also available on HK. still a decent product which I can recommend. can also be used for esc servo wires.

quite big and heavy, well they are bigger than the standard ferrite rings that sometimes come with my esc's. this is gonna peev my off adding extra weight which should not be there, damn i knew i shudda glued in twisted servo wires to my servos.
