*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%.

*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%.
†Maximum Capacitance Change @ 125ºC=+20%.
New values are in red.
