Insulation Resistance
Dielectric Strength
Capacitors withstand a DC potential of 130% 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
UNLYTIC ®technology provides a dry lm solution for electolytic capacitor replacement, oering ten (10)
times the current density and three (3) times the over voltage protection. For safety, eliminates the
possibility of caustic electrolyte leakage and its harmful eects to the environment.
For Switching power supplies where high voltages at elevated temperatures in addition to high
dv/dt as well as peak current are also required.

Marking And Date Code
All capacitors are marked with company initials "EC", corporate logo or EC trademark—in addition to type UP37, capacitance,
tolerance, rated DC working voltage and date code. The rst 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 Certied 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.
