Neosid Ferrite/iron powder torroid 17-742-22 6pcs £2.50
17-742-22 Neosid Ferrite/iron powder torroid
This is an old obsolete ring similar to 17-732-22 just we think this size is bigger, we believe it to be an iron powder core for RF use colour Grey made by Neosid in the UK
outer diameter 28mm inner diameter 20mm width approx. 10mm
at a guess its a 50khz - 1mhz core maybe higher as not so heavy
probably suitable for LF and small dc inverters and transformers
6pc for £2.50 make it worth buying for testing
