The FKC08 series offer 8 watts of output power from a package in an IC compatible 24pin
DIP configuration. FKC08 series have 2:1 wide input voltage of 9-18, 18-36 and 36-75VDC.
The FKC08 features 1600VDC of isolation, short-circuit protection and as well as five sided
shielding. All models are particularly suited to telecommunications, industrial, mobile
telecom and test equipment applications.

Note
1. The FKC08 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.
Simulated source impedance of 12uH. 12uH inductor on series with + Vin.
3.
The ON/OFF control pin voltage is referenced to negative input.
4.
BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment)
5.
Maximum value at nominal input voltage and full load of standard type.
6. Typical value at nominal input voltage and full load.
7. Test
by minimum Vin and constant resistor load.
