FAE Expert Insights
"The MKP-X2-0.47uF is my standard recommendation for 200-300W power supply input filtering. The 0.47uF value provides excellent attenuation in the 100kHz-1MHz range where switch-mode noise is most problematic. I always verify that customers understand X2 capacitors are for line-to-line only - never use them for line-to-ground applications. The 275V AC rating is conservative for 230V mains, providing good margin for voltage transients. One design tip: place X2 capacitors as close to the AC input connector as possible for maximum effectiveness."
Excellent choice for industrial applications
