Ceramic capacitor code ?
In my junk I have quite a few dirty orange disc ceramic capacitors
marked EKC CK63Y 103Z and EKC CK61Y 102Z. I know that they are 0.01 and 0.001 uufd respectively but I can't find anything on the working voltage. Anyone out there have any ideas? -- Thanks & 73 Hank WD5JFR |

put finger to keyboard and composed: In my junk I have quite a few dirty orange disc ceramic capacitors marked EKC CK63Y 103Z and EKC CK61Y 102Z.

Anyone out there have any ideas? http://www.searchlighttech.com/searc...part=CK63Y103Z ERIE CK63Y103Z .01MFD-1KVDC http://www.usbid.com/search/AddPartNoLogin_action.cfm CK63Y103Z .01MFD-1KVDC ERIE Military specs for CK61 and CK63 capacitors: http://www.dscc.dla.mil/Downloads/Mi...l11015ss12.pdf http://www.dscc.dla.mil/Downloads/Mi...015ss10am1.pdf FWIW, this supplier lists capacitors by Murata Erie: http://www.capacitorsupply.com/csi-lc.htm The US Patent Office lists several patents for capacitors, including ceramic types, assigned to Erie Technological Products Inc, eg ... US Pat. 3153753 - Filed Jan 25, 1961 US Pat. 3467898 - Filed Aug 7, 1968 US Pat. 3988651 - Filed May 23, 1975 US Pat. 4388415 - Filed Sep 30, 1981 In 1981 Erie was acquired by Murata: http://findarticles.com/p/articles/m..._20069789/pg_4 "In 1981, Mr. Murata decided he would like to acquire Erie Technological Products, which at that time was an old-line North American manufacturer of capacitors." BTW, my guess is that the CK61Y capacitor has a rating of at least 500V, possibly 1KV, if "Y" is the voltage designator. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |
