Type SF Lighting Capacitors, 90 °C Rated, Oil Filled
AC Rated, Oil Filled/Impregnated, Metallized Polypropylene Capacitors
For better performance in HID Lighting and HV Bal-
lasts, Type SF oval and round oil filled metallized poly-
propylene lighting capacitors are built for operating in
the high temperature environments for high intensity
discharge (HID) lighting and other high voltage ballast
applications. Each HID catalog capacitor includes an
external resistor that discharges the capacitor to less
than 50V in one minute, and the oil filled process assures
better reliability than dry capacitors.
Highlights
• Protected: UL recognized under E71645
• Meets EIA Standard EIA-456-A
