**6 Volt product equivalent to 6.3 volt product.  
(1) To complete KEMET Part Number, insert M for ±20% tolerance or K for ±10% tolerance.  
Higher voltage ratings, lower ESR, and tighter capacitance tolerance product may be  
substituted within the same size at KEMET's option. Voltage substitutions will be marked  
with the higher voltage rating.

*Extended Values  
**6 Volt product equivalent to 6.3 volt product.  
(1) To complete KEMET Part Number, insert M for ±20% tolerance or K for ±10% tolerance.  
Higher voltage ratings, lower ESR, and tighter capacitance tolerance product may be  
substituted within the same size at KEMET's option. Voltage substitutions will be marked  
with the higher voltage rating.  
#Maximum Capacitance Change @ 125ºC=+15%.
