: Output capacitor (47 to 100 µ F)
: Oscillation prevention capacitors
: Protection diode
(Approx. C
These capacitors are required if the input line contains inductance
or the wiring is long. Especially at low temperatures, tantalum
capacitors are recommended for C
This diode is required for protection against reverse biasing of the
input and output. Sanken EU2Z is recommended.
