Marking And Date Code

All capacitors are marked with company initials "EC", corporate logo or EC trademark—in addition to type MP3, capacitance, tolerance, rated 

DC working voltage and date code. The first two digits of the date code represent the year, the second two digits the week, i.e., 1252 is the 

52nd week of 2012, 1202 is the second week of 2012.

Quality Assurance

Major emphasis is placed on quality assurance. EC is an ISO 9001 and AS9100 Certified Company. Raw material inspection and the use of 

SPC manufacturing procedures assure the highest quality standards. Procedures are fully described in the EC Quality Control Manual. 

Electronic Concepts will continue to advance the state-of-the-art by utilizing leading edge technology, compact capacitor designs and 

establishing reliability procedures.

The  MP3  capacitor  series  further  enhances  the  existing  UL3  product  offering.    The  MP3  incorporates  the  established 

UNLYTIC

®

 film technology with new cost effective packaging, which provides higher storage capacity and voltage creepage 

protection.  The capacitor is isolated from the outer case, allowing for simple package and connection mounting.  The product 

series is well suited for bulk DC storage, especially useful in DC link converter/inverter applications.
