VOLTAGE

DC Voltage Rating: BE=700VDC, BJ=900VDC, BM=1100VDC, BN=1200VDC,

BT=1600VDC, CA=2000VDC, CD=3000VDC
CAPACITANCE IN PICOFARADS

The first two digits are significant, the third represents the number of zeros

(e.g 448=4,400,000,000pF) 

Marking And Date Code

All capacitors are marked with company initials "EC", corporate logo or EC trademark—in addition to type UL9, capacitance, tolerance, rated 

DC working voltage and date code. The fi�rst 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 UL9 series uses the company’s proven Unlytic

® 

technology which significantly reduces weight and size optimized for DC 

power conversion.  Additionally, the product incorporates traditional dry film “self-healing” properties, providing long life and 

reliability.
