General Specifications

The Type 725M Orange Drop

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.
