Other part number options:
1- Standard with tin terminations (14th character = T). Tin/lead terminations is also available (14th character = H).
Also available on large (13 inch) reels. Add 7280 to the end of the part number.
Higher voltage ratings and tighter tolerance product including ESR may be substituted within the same size at KEMET's option. Voltage substitutions will be marked
with the higher voltage rating. Substitutions can include better than series.
