General Specifications
The Type 725M Orange Drop
®
is designed and manufactured for operation in a wide range of demanding envi-
ronments and applications. Type 725M capacitors are wound from the most reliable metallized polypropylene
film available and are protected by a rugged conformal coating of orange epoxy. They may be operated up to
+105°C with proper derating.
The 725M series is an ideal choice for a variety of commercial and industrial electronic applications, from
power supplies and amplifiers, to inverters and lighting ballasts. The 725M series is constructed of the highest
quality polypropylene film with a vacuum deposited metal electrode. Metallized film offers specific clearing/
self-healing characteristics that remove a fault or short in the dielectric film by vaporizing the metal electrode
surrounding the defect and isolating the area.
Operating Temperature Range:
The standard operating temperature range for
polypropylene film is -55°C to +85°C. The 725M
may be operated at full voltage within this
temperature range.
The 725M may be operated up to +105°C
provided the DC working voltage is reduced
to 50% of the +85°C rating (full rating).
For more specific details regarding operation
above +85°C please contact our application
engineering department.
The maximum operating temperature for the
725M series is +105°C.
Dielectric Withstanding Voltage:
Units shall withstand a DC potential of 150%
of rated voltage applied between terminals for
not more than 2 minutes.
AC Voltage Applications:
The A-C component of the 725M's voltage rating
has been specified to assure that corona will not
be encountered when the capacitor is operated
within the noted specifications. We encourage
you to contact us if you have any concerns about
operating voltage, temperature limits, etc.
Lead Bend Test:
After 3 consecutive 180° bends. No damage.
DC Voltage Life Test:
500 hours at +85°C at 125% of rated voltage. After
test; capacitance shall not have changed by more
than ±5% of initial value, insulation resistance shall
not have decreased by more than 50% of initial
requirement and dissipation factor shall not have
increased to more than 0.1%. In addition, there should
be no open or short circuits, and no sign of visible
damage.
AC Voltage Life Test:
Minimum of 500 hours at +85°C at 60 Hz. AC test
voltage applied at 110% of AC rating. After test,
capacitance shall not have changed by more than 3%,
insulation resistance shall not have decreased by
more than 50% of initial requirement, and dissipation
factor shall not have changed by more than 0.03%.
Measurements made at 1 KHz.
Additional Notes:
While it is not possible to list every detail of testing
that we perform or every combination of capacitance
value, tolerance, etc. that is available, we strongly
encourage you to please contact us with your specific
requirements. Thank you.
