* 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.
(2) To complete KEMET part number, insert lead material designation from page 4.
Higher voltage rating, 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 @ 125°C = +15%
† Maximum Capacitance @ 125°C = +20%
