Description
YEA R
The RP12-A series DC/DC converters are certified to UL 60950-1 and cUL 60950-1. This makes
them ideal for all telecom and industrial applications where approved safety standards are required.
The DIP24 package is available in both pinned and SMD case styles and meets military standards for
thermal shock and vibration tolerance.
