Install an external capacitor Cin, with more than 33 µF, between +Vin and -Vin input pins for low line noise and for stable operation Tc= -20 °C to +100 °C electrolytic or, Tc= -40 °C to +100 °C ceramic capacitor. When the line impedance is high or the input voltage rises quickly at start-up (<10 µs), install a capacitor Cin between +Vin and -Vin input pins (within 50 mm from pins). 2.

Mechanical Details Derating Use with conduction cooling (e.g. heat radiation by conduction from the aluminium baseplate to the attached heatsink). NOTE: Derating curve shown is based on the aluminum baseplate temperature. In the hatched area, the specification of ripple & noise is different from other areas. Connection For Standard Use In order to use the converters, it is necessary to wire as shown.
