components to operate, but the use of a low ESR capaci-
tor (approximately 10 uF, ESR <1.0Ω at 100 kHz) mounted
close to the converter input pins is recommended.
For 48 VDC input units, an input capacitor should always
be used. Dependent upon the application, a value be-
tween 4.7 µF and 47 uF should be suffi cient.
