Safety Capacitor Selection Guide: X vs Y Capacitors Explained

Safety capacitors are used on power lines to suppress electromagnetic interference (EMI), divided into X-type and Y-type. X capacitors are connected between the L and N lines to suppress differential-mode interference; Y capacitors connect between L/N lines and ground to suppress common-mode interference. Key selection parameters include voltage rating, capacitance and certification standards (UL, CQC, VDE). Lixing Tech offers a complete X1/X2/Y1/Y2 safety capacitor range — contact us for pricing.
