Dielectric Strength
Capacitors withstand a DC potential of 150% rated
voltage for two (2) minutes without damage or
breakdown. Test voltage is applied and discharged
through a resistance of 1 OHM per volt minimum, and at
25°C.

ADDITIONAL INFORMATION
The type 5MC is a new miniature polycarbonate film capacitor that is designed specifically for
switch-mode power converters. It is the first of a series developed by Electronic Concepts for
switch-mode applications that offers a miniature configuration to conserve printed circuit board space,
with low ESR, excellent ripple capacity, and high resonant frequency.

Marking And Date Code
All capacitors are marked with company initials "EC", corporate logo or EC trademark—in addition to type 5MC, 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., 0952 is the 52nd week of 2009, 0902 is the second week of 2009.
Quality Assurance
Major emphasis is placed on quality assurance. EC is an ISO 9001-2000 and AS9100:2004 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.
