Description
The RP08-A series DC/DC converters are certified to UL60950-1 and cUL60950-1. 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 ther-
mal shock and vibration tolerance.
