General Information
Product Description
RFI suppressors are a special class of capacitors for use on the AC power line inputs to electronic or electrical equipment.
Their purpose is to eliminate or attenuate radio frequency interference voltages originated in the units connected to the
same AC power branch and prevent them from mutually disturbing their operations.
They must endure very harsh conditions existing on the 60/50Hz AC power lines — including voltage surges and
transients. Therefore, they must meet the requirements of EN 132-400 and IEC 384-14, 2nd edition 1993 standards
enforced by international safety certification bodies, as well as UL-1414 and UL-1283 in USA.
Our RFI capacitors are made with metallized polypropylene or polyester films of the highest quality and have self healing
properties. There are two classes of these capacitors: Line-to-Line X2 Class, and Line-to-Ground Y2 Class.
We have three series of X2 — WXP and WXPC series rated at 300VAC and *275VAC — and two series of Y2
— WYP and WYE rated at 275VAC and 250 VAC. WXP, WXPC (smaller dimensions) and WYP series are made with
polypropylene film. WYE series is made with polyester film.
While polypropylene and polyester series are compatible, polypropylene dielectrics are more popular worldwide and
have smaller dissipation factor (DF) improving operation at higher frequencies. Also, due to larger production volumes
polypropylene capacitors are less expensive.
World Products has excelled in serving customer needs, providing a full line of protection products. We also offer to our
customers the technical support of our Applications Laboratory equipped with industry standard, test equipment that can
duplicate most safety agency testing.
Our manufacturing plant has received the Certificate of Quality Assurance System according to the ISO9001
standard.
We invite you to contact World Products and put us to the test. We can best prove our “commitment to excellence” by
actually working for you.

Definition of Terms
Capacitance
Capacitance values are measured and specified for 1KHz at 25°C
Dissipation Factor (DF)
The measure of the suppressor’s dielectric loss at 1KHz also called tangent of loss angle. It is the ratio of loss power to
the reactive power across capacitor that is customarily expressed in % (Ratio = tanF = .01 —> DF = 1%). At large DF and
operation above specified limits loss power may cause significant internal heating leading to destructive breakdown. All of
our suppressors are designed and made with top quality materials to minimize DF.
Insulation Resistance (IR)
Measurement of the specified IR is made after applying 100 VDC for one minute at 25°C. The proprietary multiple
dielectric design of our suppressors provides higher insulation resistance than single dielectric suppressors.
Climatic Category
According to international safety standards, IEC 60384-14, and IEC 60068-2, suppressors must be categorized according
to the rated lowest temperature / the rated highest temperature / the number of days samples are subjected to damp
humidity test — in our case: 56 days — which is the absolute maximum rating category.
Rated Voltage
The rated voltage is the maximum RMS AC voltage which can be applied continuously within the specified Rated
Temperature range.
Rated Temperature Range
The maximum low and high ambient temperature at which the rated voltage can be continuously applied.
Endurance Life Test
Production samples are subjected to a periodic life endurance testing to comply with international safety approval
standards. These tests specify that the suppressor shall have 1.25 x rated voltage (X2) and 1.7 x rated voltage (Y2)
applied for a period of 1,008 hours at an elevated temperature of 100°C. We test our WYE suppressors with the above
endurance voltages, not only at the time of type approval, but also at 6 month intervals. In addition to the above voltages
applied constantly, 1000 VAC is applied once each hour for 0.1 second. Both the steady state and momentary (0.1 sec)
1000 VAC voltage is applied through a 47 ohm ± 5% resistor simulating the high frequency impedance of AC mains. After
the endurance life test, capacitance shall not deviate more than 5% of the initial value, IR shall not be less than 50% of
the initial value and DF shall not be greater than the specified. The combined stress of both voltages applied is proof that
these suppressors are capable of withstanding high line conditions that are often present on the AC mains.
dv/dt
The maximum acceptable voltage rate of change per µsec of rise or fall time as defined below:

dv/dt = ————
