1. 20 mHz bandwidth. An external 2.2 µf ceramic
capacitor is recommended to be placed from +V out
to -V out.
2. Requires a 2.2 µf, 100V film capacitor connected
between +V in and -V in to meet FCC class A and
ETS300-386-1 requirements for conducted noise.
Consult Factory for filtering information to meet FCC
class B, VDE or EIC specifications.
