Filmlytic
Film Capacitor Alternative to Aluminum Electrolytics
The new Filmlytic offers all the advantages of metalized film capacitor technology in values
and sizes that until now were only available from aluminum electrolytics. Dearborn specifical-
ly designed the Filmlytic capacitor series to provide a non-polar construction with greater
current density and higher over voltage protection; all in the same package dimensions and
terminations as standard electrolytics.
Not only are the Filmlytics available in higher voltage ratings, up to 1800 VDC, they have
vastly superior performance characteristics over the operating temperature range from -55C to
+85C. Their non-impregnated construction eliminates harmful electrolyte leakage making
them friendly to surrounding equipment and the environment. This dry construction and the
self-healing feature of metalized film electrodes, extends useful service life, improves
reliability, and provides for a long shelf life.
Maximize your power system design, specify Dearborn's Filmlytic in your products and
deliver improved reliability, longer life and superior performance to your customers today.

Quality Assurance Testing
INSPECTION: Prior to shipment, Filmlytics are 100% inspected for Capacitance value,
Dissipation and ESR values, DC Voltage Test, and Insulation Resistance. Sample inspection is
then performed to assure that the Filmlytic meets Dearborn’s exacting standards of workman-
ship and mechanical performance.
HUMIDITY RESISTANCE: When tested for 250 hours at 40°C and 95% relative humidity in
accordance with MIL-STD-202 Method 103B, Filmlytics shall not: exhibit visible damage,
change in capacitance value by more than 5% of the initial value, have an insulation resistance
value lower than 20% of the initial limit, or exhibit a 1KHz DF of greater than 2%.
LIFE TEST: When subjected to 110% of rated voltage at 85°C for 250 hours, Filmlytics shall
not: exhibit a permanent short or open, change in capacitance value by more than 3% of initial
value, have an insulation resistance value less than one third of the initial limit, or have a 1KHz
DF greater than 2.5%.
