Dissipation Factor
Polypropylene has an intrinsic dissipation factor of less than 2.1
x 10-4 over the operating temperature range of -55°C to +105°C
and frequencies to 1MHz.
Dielectric Strength
Capacitors withstand a DC potential of 1.3 x rated
voltage for one (1) minute without damage or
breakdown. Test voltage is applied and discharged
through a minimum resistance of 100 OHM per volt
minimum.
ADDITIONAL INFORMATION
The combination of physical and electrical properties it offeres encompasses low inductance with high
current carrying capability – and a low profile to make the most efficient use of system space and
increased cooling efficiency. Plus an in-house developed, “specific to the task” thermoplastic formulation
for the enclosure, improves thermal conductivity. There is also an integrated flange with pre-drilled holes
to simplify mounting.
The UNLYTIC
®
UL3 SERIES, with its introduction, the designer has a film capacitor for high
power filter systems that will maximize space utilization, performance and reliability. With the
added potential for measurable production cost savings.

CAPACITANCE IN PICOFARADS
The first two digits are significant, the third represents the number of zeros
(e.g 506=50,000,000pF)
TOLERANCE
Standard tolerance is ±10%. Tolerances of ±20% and ±5% are also
available.
Marking And Date Code
All capacitors are marked with company initials "EC", corporate logo or EC trademark—in addition to type UL3, 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.
