CONSTRUCTION
The "FILMET" capacitor is constructed using low loss polypropylene film dielectric
on which a thin layer of metal has been deposited to one side to serve as the
electrode. The two sheets are displaced forming a low loss non-inductive
(extended foil) capacitor. Both ends of the windfng are spray-metallized to provide
a means to attach the copper tabs. The tabs are then spotwelded to the rivet on the
underside of the cover and the cover is sealed to the case by a double-lock roll seam.
The unit is completely filled with LEKTROL, a non-PCB fluid which is biodegradeable,
low toxic, and environmentally compatible. The thin layer of metal which is aeposited
on the film dielectric not only replaces the conventional aluminum foil electrodes
but is self-healing, resulting in higher operating voltages and longer lite.
CHARACTERISTICS
Polypropylene film is a low loss dielectric possessing hih voltage stress capabilities.
These characteristics allow the polypropylene "FILMET capacifor to consume less
energy and result in smaller physical size per volt-ampere than the all paper or
film-paper capacitor.
CASE RUPTURE PROTECTION
Since the non-PCB impregnant is a combustible liquid, RONKEN has incorporated
into the capacitor cover assembly an internal pressure sensitive current interrupting
device. This minimizes capacitor case rupture by reacting to the cover bulging.
The cover bulges due to the pressure build-up caused by the gassing and excessive
temperature associated with end of life capacitor failures. As tfie cover bulges, the
pressure sensitive interrupter internally disconnects the capacitor terminals from the
external power source. Therefore, it is necessary to allow a minimum of 1/2" clearance
above the capacitor terminals tor the cover to bulge.
RON KEN capacitors incorporating the pressure sensitive interrupter are
U.L. recognized under file #E78260.
CAPACITANCE
The capacitance is rated in microfarads (MF) at 25°C. The capacitance change over
the operating temperature range of -40°C to +90° C shall not exceed t 5%.
DISSIPATION FACTOR
The dissipation factor shall not exceed 0.1 % when measured at the 60 HZ rated
voltage and any case temperature between 25° C and 90°C.
TEMPERATURE
The operating case temperature range is -40°C to +70 °C. However, the 70°C capacitors
may be operated up to 90° C maximum hot spot case temperature with proper
voltage derating.
FREQUENCY
The capacitor may be operated at any sinusoidal frequency up to 66 HZ.
The capacitors are designed to provide a minimum of 60,000 hours life with a 94%
survival when operated at rated voltage, frequency, and case temperature.
Exceeding the capacitor ratings without proper derating will result in a reduction
of full rated life.
LEAKAGE CURRENT
The leakage current shall not exceed 30 microamps when measured with
115 VAC 60 HZ applied between the shorted capacitor terminals and case.
