    \$\begingroup\$ It looks like an old soviet film capacitor \$\endgroup\$ – venny Aug 24 '14 at 15:16
  • \$\begingroup\$ The "6800" marking would support that theory, although I've never seen any capacitor built like that before. \$\endgroup\$ – TDHofstetter Aug 24 '14 at 15:38

    \$\begingroup\$ Better focus would be much more useful - if camera will not focus at that distance hold it furthe away - small and shrp is better than large and fuzzy. More light almost always helps. \$\endgroup\$ – Russell McMahon Aug 24 '14 at 16:18

It is soviet silver mica capacitor. Old but still good quality. 500B (read as 500V) is the maximum voltage. 6800 is 6800pF or 6.8nF. 5% is the capacitance tolerance.

  • \$\begingroup\$ thanks, found it in some old circuit board, there is a lot more of them \$\endgroup\$ – theraginggamer Aug 24 '14 at 15:40
