Note

1.

The FEC15 series required a minimum 10% loading on the output to maintain specified

regulation. Operation under no-load condition will not damage these devices, however they may

not meet all listed specification

2.

Please add an external filter at converter input terminals when measuring input reflected ripple,

as figure 1.

L: Simulated source impedance of 12μH

C: Nippon chemi-con KMF series 100μF/100V

3.

The ON/OFF control is option function. There are positive logic and negative logic. The pin

voltage is referenced to negative input

To order positive logic ON-OFF control add the suffix-P (Ex: FEC15-24S05-P)

To order negative logic ON-OFF control add the suffix-N (Ex: FEC15-24S05-N)

4.

BELLCORE TR-NWT-000332. Case 1: 50% Stress,

Temperature at 40ºC. (Ground fixed and controlled

environment)

5.

Heat sink is optional and P/N: 7G-0020A
