| Nov 20, 2015 at 13:49 | comment | added | Andy aka | yeah it's 217. Silly me. | |
| Nov 20, 2015 at 13:26 | comment | added | Roman Matveev | Thank you! Are you sure that it is MIL-HDBK-417F not MIL-HDBK-217F. 217 is actually about the thing you're talking about. 417 I wasn't able to find :( | |
| Nov 20, 2015 at 11:28 | comment | added | Andy aka | If you want to know how long the coil will last there is the exceelant document entitled MIL-HDBK-417F. You can download it freely and look up the reliability of inductors. The formulas in the document are quite accessible and you will be able to derive an answer of MTBF that is based on literally thousands of failure events. Give yourself 4 hours to digest the methodology though because you will likely be facing a couple of concepts you haven't encountered before. | |

| Jun 2, 2015 at 14:24 | comment | added | Andy aka | @RomanMatveev Each Bill of material will give you a bigger number of options for both (all) inductors used in your specific design. I recommend that you sift thru a few of these and get a feel for this (these) components. I felt that information that the manufacturer recommends for these inductors is better than trying to engineer a philosophy on what is right or wrong. | |
| Jun 2, 2015 at 14:21 | comment | added | Roman Matveev | The question was mostly about inductor coil voltage strength, not about LNK304 implementation. However thank you anyway for pointing me to this huge source of reference designs - I didn't know that. | |
