Safety and Installation Instruction:
Fusing Consideration
Caution: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of sophisticated power architecture. To 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 maximum rating of 3A. Based on the information provided in this data
sheet on Inrush energy and maximum DC input current; the same type of fuse with lower rating can be used.
Refer to the fuse manufacturer’s data for further information.
MTBF and Reliability
The MTBF of the LANCW12 single output series of DC/DC converters has been calculated using Bellcore
TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40°C (Ground fixed and controlled
environment). The resulting figure for MTBF is 2.75 × 10⁶ hours.
MIL-HDBK 217F NOTICE2 FULL LOAD, Operating Temperature at 25°C. The resulting figure for MTBF is
1.078 × 10⁶ hours.
