 Marking

The indications listed below should be given on the surface of a capacitor.

(1) Polarity
(2) Rated DC voltage : Due to the small size of AS case, a voltage code is used as shown below.
(3) Visual typical example (1) voltage code (2) capacitance code

: The polarity should be shown by bar. (on the anode side)
