RoHS Compliance
WXPC 0.010 to 1.5μF/275VAC class X2 This is to certify that the referenced RFI suppressors purchased
from World Products, LLC comply to a maximum concentration
value of 0.1% by weight in homogeneous materials for lead (Pb),
mercury, hexavalent chromium, polybrominated biphenyls (PBB)
and polybrominated diphenyl ethers (PBDE) and of 0.01% weight
in homogeneous materials for cadmium and are in compliance with
Directive 2002/95/EC of the European Parliament and of the Council
of 27 January 2003 on the restriction of the use of certain hazardous
substances in electrical and electronic equipment (RoHS Directive)
as of July 2005 (date code marking starting 0527). Additionally “R”
marking (per marking specication) is initiated starting with date
code 0544 to further identify RoHS compliant products.

Note
All our capacitors listed above have Climatic Category: IEC 40/100/56 C,and Operating Temperature Range: -40 to +100°C.
Definition of Terms
Capacitance
Capacitance values are measured and specied 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 specied limits loss power may cause
signicant 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 specied 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 specied 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
specied. 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.
