Kind friends...
It has been my observation that many capacitors marketed as 'silver mica' and/or 'dipped mica' (and, indeed, most devices featuring their characteristic 'form-factor') bear, as an apparent identifying marking; 'EM' (as opposed to the standard 'SM') -- FWIW I had thought, perhaps, 'Etched Mica'? Howbeit I am unable to locate support for this - nor do the several (on-line and hard-copy) electronics resources I've had occasion to examine make reference to the 'EM' capacitor marking...
Inasmuch as my application is critically dependent upon 'silver-mica characteristics' Any insight into this matter will be greatly appreciated!
Many advance thanks!
Best regards
