**** = WXP, WXPC
- All measurements are based on 5mm lead lengths at nominal C values.
- Actual resonant frequencies will depend also on the total length of the circuit connections to the capacitor terminals and capacitor's actual C value. The tolerances for our capacitors are: ±10% for WXP, WXPC series of X2 class. ±20% for WYE, WYP Series Y2 class.
- WYE is made with metallized polyester film. WXP, WXPC and WYP are made with metallized polypropylene film.
