Note A: Input filter components (C1, L , see circuit below) are used to help meet conducted emissions requirement for the module.
These components should be mounted as close as possible to the module; and all leads should be minimized to decrease radiated noise.
Note B: An external filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5.
The filter capacitor suggested value of 220uF/100V.

Notes: Add “-K” suffix for ordering, heat sink is affixed with thermally dissipative adhesive tape.
See derating graph for temperature performance. Heat sink material is anodized (black) aluminum, adds weight 11.2g to
total mass (42.2g). Thermal impedance of converter is: with heat sink 10Ԩ/W and 12Ԩ/W without heat sink.
