Type SF Motor-Run and Power Supply Capacitors
Oil Filled/Impregnated, AC Rated, Metallized Polypropylene Capacitors
Type SF, AC rated metallized polypropylene capacitors provide
starting torque and power factor correction for split phase
motors typically used in refrigeration and air conditioning motor-
run applications. Type SF also may be used to provide noise
suppression, voltage regulation and line current reduction in power
supply applications.

Note: The capacitor’s safety pressure
interrupter is designed to disconnect
the capacitor element as the cover
expands upward due to gas pressure
build up. Catastrophic failure may
result if movement of the cover and
or terminals are restricted. Rigid bus
bars are not recommended as they
may restrict movement of the cover
or terminals. Customers are advised to
provide at least 0.5” clearance above
the cover to allow for its expansion.

Notice and Disclaimer:
All product drawings, descriptions, specifications, statements, information and
data (collectively, the “Information”) in this datasheet or other publication are subject to change. The
customer is responsible for checking, confirming and verifying the extent to which the Information con-
tained in this datasheet or other publication is applicable to an order at the time the order is placed. All
Information given herein is believed to be accurate and reliable, but it is presented without any guaran-
tee, warranty, representation or responsibility of any kind, expressed or implied. Statements of suitability
for certain applications are based on the knowledge that the Cornell Dubilier company providing such
statements (“Cornell Dubilier”) has of operating conditions that such Cornell Dubilier company regards
as typical for such applications, but are not intended to constitute any guarantee, warranty or representa-
tion regarding any such matter – and Cornell Dubilier specifically and expressly disclaims any guarantee,
warranty or representation concerning the suitability for a specific customer application, use, storage,
transportation, or operating environment. The Information is intended for use only by customers who
have the requisite experience and capability to determine the correct products for their application. Any
technical advice inferred from this Information or otherwise provided by Cornell Dubilier with reference
to the use of any Cornell Dubilier products is given gratis (unless otherwise specified by Cornell Dubilier),
and Cornell Dubilier assumes no obligation or liability for the advice given or results obtained. Although
Cornell Dubilier strives to apply the most stringent quality and safety standards regarding the design
and manufacturing of its products, in light of the current state of the art, isolated component failures may
still occur. Accordingly, customer applications which require a high degree of reliability or safety should
employ suitable designs or other safeguards (such as installation of protective circuitry or redundancies
or other appropriate protective measures) in order to ensure that the failure of an electrical component
does not result in a risk of personal injury or property damage. Although all product-related warnings,
cautions and notes must be observed, the customer should not assume that all safety measures are indi-
cated in such warnings, cautions and notes, or that other safety measures may not be required.
