(1) To complete KEMET Part Number, insert M for ±20% tolerance or K for ±10% tolerance.
(2) To complete KEMET Part Number, insert T, H, G, or S lead material designation as shown on page 15.
*Extended Values
**6 Volt product equivalent to 6.3 volt product.
#Maximum Capacitance Change @ 125ºC=+15%.
†Maximum Capacitance Change @ 125ºC=+20%.
Higher voltage ratings and tighter tolerance product may be substituted within the same size at KEMET’s option.
Voltage substitutions will be marked with the higher voltage rating.
