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.

Baseplate

Slotted (Style 1)

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".

Pin style

Short (Style 1)

For long pin configuration add “L” to the end of the

part number. See page 7 for pin dimensions.

MODULE MECHANICAL SPECIFICATIONS

Note: For important information relative to applications where the converter modules are subject to continuous dynamic loading,
