Insulated sleeving

An insulating sleeve of approved material is placed over the ceramic Y capacitor, at higher total cost. Read how the sleeve can be eliminated.

Keep-out zones

An open area is left around the ceramic Y capacitors, creating a footprint penalty. Read how the keep-out zone can be eliminated.
