I have a ferrite (?) toroid core that is approximately 17mm O.D. x 10mm I.D. x 6.7mm high. It is grey with a smooth, epoxy-like coating and was purchased at a surplus store. It has an identifier number on it: 2D10-55115-A2-2. That number in Google simply finds the surplus store from which I bought it. The store has no other information. Alldatasheet and Octopart do not show it. PartMiner shows the number, but again no information.
Does anyone recognize that numbering system as being characteristic of any manufacturer? And against all hope, are there any simple ways to approximately identify the type of ferrite used in a particular core? Thank you. John
