Green ferrite ring inductor 425UH 2pcs £3.00 item 2031
Green Ferrite ring inductor 425uh
This is a ferrite ring size 32mm x 13mm hole size 18mm colour green
we do not have information about this ferrite but they have a high quality coating and do not look like the cheaper styles.
These would be used in power supply and EMC lighting applications, basically very low frequency, the ones we have are mounted but not soldered to a small pcb, now it is wound as 3 x 425uh inductors, the wire can be re-used as it has not been soldered.
If anyone has any further info please let us know, one supplier was saying these are a Mzinc coil with a al 7000 but we have no data to confirm that, good for playing about with VLF stuff
