NH020-Series Power SIPs:

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress

ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the

operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the

device reliabiltiy.

output. See the Thermal Considerations section for more details.

† The –40 °C operation is optional. See Ordering Information section.

Electrical Specifications

Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions.

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power SIP can be used in a wide variety of applications, ranging from simple stand-alone operation to an

integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however,

to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow

fuse with a maximum rating of 10 A (see Safety Considerations section). To aid in the proper fuse selection for the given appli-

cation, information on inrush energy and maximum dc input current is provided. Refer to the fuse manufacturer’s data for fur-

ther information.
