​METALLIZED POLYPROPYLENE CAPACITORS 220 - 660 AC

Model: P91P09206H06

APPLICATIONS

Motor Run ---- HID Lighting ---- Ferro-Resonant Power Supplies ---- Filters ---Battery

Chargers ---- Power Factor Correction ---- and Others.

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 hi􀁶h 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.
