V. How do I now the ratings of the "Mini Fuses"? All they say is 7K,
9K, etc......
--------------------------------------------------------------------------
Shown on the right are the Hitachi Pico Fuses.
As can be seen, they have an identifying Label.
These values represent mA ratings.
Example: 10K would mean 10K mA. Move the decimal three places to the left
and you would have 10 Amps.
(10K = 10K mA = 10,000 mA = 10A)
Another Example:
(500 = 500 mA = 0.5 A = 1/2 Amp)
