The YKC03 series offers 3 watts of output power from a package in an IC compatible
24pin DIP configuration without derating to 71ºC ambient temperature. YKC03 series
have 2:1 wide input voltage of 9-18, 18-36 and 36-75VDC. The YKC03 features
1600VDC of isolation, short-circuit protection and as well as five sided shielding. A safety
designed meet to EN60950 and UL1950. All models are particularly suited to
telecommunications, industrial, mobile telecom and test equipment applications.
