FAE Expert Insights
"The MKP-Y2-2200pF is the most common Y2 capacitor I specify for general-purpose power supplies. The 2200pF value provides good high-frequency common-mode attenuation while keeping leakage current low. Remember that Y2 capacitors are for line-to-ground ONLY - using them line-to-line violates safety standards. The 5kV impulse rating is critical for handling lightning-induced transients. One important consideration: total Y capacitance per device is limited by leakage current regulations - typically 3300pF max for portable equipment. Always calculate total leakage current when using multiple Y caps."

Frequently Asked Questions
What is the maximum leakage current with this capacitor?
At 250V AC 50Hz, leakage current is approximately 0.35mA. Total device leakage must comply with safety standards (typically <0.25mA for Class II, <3.5mA for Class I). For detailed specifications and application support on faratronic MKP-Y2-2200pF-250V, refer to the datasheet or contact our team.
Calculate total leakage current for all Y capacitors in your design. Consider using lower capacitance if leakage limits are strict.
Can Y2 capacitors fail short circuit?
Y2 capacitors are designed with self-healing properties and should not fail short under normal conditions. Safety standards require that any failure be open-circuit or high-resistance. For detailed specifications and application support on faratronic MKP-Y2-2200pF-250V, refer to the datasheet or contact our team.
For critical safety applications, specify Y2 capacitors from reputable manufacturers with full safety certifications.
What is the difference between Y1 and Y2 capacitors?
Y1 capacitors are rated for 500V AC and provide basic insulation. Y2 capacitors are rated for 250V AC and provide reinforced or double insulation. Y2 is more common in 230V applications. For detailed specifications and application support on faratronic MKP-Y2-2200pF-250V, refer to the datasheet or contact our team.
For 230V AC applications, Y2 capacitors are typically sufficient. Use Y1 only if specifically required by your safety agency.
How do I test Y2 capacitors for safety compliance?
Y2 capacitors require impulse voltage testing at 5kV and AC voltage testing at 1500V. These tests verify insulation integrity and are performed during manufacturing. For detailed specifications and application support on faratronic MKP-Y2-2200pF-250V, refer to the datasheet or contact our team.
For incoming inspection, verify capacitance, dissipation factor, and insulation resistance. Full safety testing requires specialized equipment.
Can Y2 capacitors be used in series for higher voltage?
No, Y2 capacitors should not be used in series for voltage sharing. Safety standards require each Y capacitor to be rated for the full line-to-ground voltage. For detailed specifications and application support on faratronic MKP-Y2-2200pF-250V, refer to the datasheet or contact our team.
For higher voltage applications, select appropriately rated Y capacitors rather than series connection.
