ELECTRICAL CHARACTERISTICS
Electrical characteristics apply over the full operating range of input voltage, output load (resistive) and baseplate temperature,
unless otherwise specified. All temperatures refer to the operating temperature at the center of the baseplate.
Note: For important information relative to applications where the converter modules are subject to continuous dynamic loading,

Over operating temperature range
Nominal input; full load; 20 MHz bandwidth
Output voltage 95% of nominal
Output voltage <250mV
10 to 100% of full load
Of nominal output voltage. For trimming below 90%
of nominal, a minimum load of 10% of maximum
rated power may be required.
Slotted baseplate (style 1) requires no designator.
For threaded baseplate add a "2" to the end of the
part number. For thru-hole add a "3".
For long pin configuration add “L” to the end of the
part number. See page 7 for pin dimensions.
