(1) To complete KEMET part number, insert M for ±20% or K for ±10%. Designates Capacitance Tolerance.
(2) To complete KEMET part number, insert T = 100% Matte Tin (Sn)-plated, G = Gold-plated, H = Standard solder coated (SnPb 5% Pb minimum), N =
Non-magnetic 100% Tin (Sn), M = Non-magnetic (SnPb). Designates Termination Finish.
Refer to Ordering Information for additional details.
Higher voltage ratings and tighter tolerance product including ESR may be substituted within the same size at KEMET's option. Voltage substitution will
be marked with the higher voltage rating. Substitutions can include better than series.
