Faratronic EMI Suppression Capacitors

X2 capacitors are used across the line (line-to-neutral) for normal mode EMI filtering. Y2 capacitors are used line-to-ground and must provide reinforced insulation for safety. Y2 capacitors have stricter impulse voltage requirements.

Use X2 for differential mode filtering across AC lines. Use Y2 for common mode filtering to ground where safety isolation is required.

Faratronic EMI capacitors are certified to IEC 60384-14, UL 60384-14, EN 60384-14, and CQC standards. They carry UL, VDE, and ENEC safety approvals. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

For international products, specify capacitors with multiple safety approvals. Check specific certifications for your target markets.

While X2 capacitors are rated for AC, they can be used in DC applications at higher voltages (typically 630V DC for X2 275V AC rated parts). Check the datasheet for DC rating. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

For DC applications, verify the DC voltage rating in the datasheet. DC rating is typically 2.3x the AC rating.

X2 capacitors typically range from 0.01uF to 10uF. Y2 capacitors are typically 100pF to 4700pF due to safety limitations on line-to-ground capacitance. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Select capacitance based on required filter attenuation. Higher capacitance provides better low-frequency filtering but increases leakage current for Y caps.

Yes, Faratronic EMI capacitors use flame retardant materials meeting UL 94 V-0 requirements. The encapsulation and case materials are self-extinguishing. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

For safety-critical applications, verify flame retardant ratings. All Faratronic safety capacitors meet stringent fire safety requirements.

EMI capacitors are typically rated for 100,000 hours at rated voltage and 85°C. Actual lifetime depends on operating voltage, temperature, and humidity conditions. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

For long lifetime, operate below rated voltage and temperature. Avoid high-humidity environments without proper protection.
