Models SM-LP-5001 and SM-LP-5002 Transformers
Change in Dielectric Withstanding Voltage
Bourns
®
line-matching transformers SM-LP-5001 and SM-LP-5002 are UL60950-approved.
UL60950 requires a dielectric withstanding voltage (DWV) of 1500 VRMS for one minute. Effective
immediately, the DWV of part numbers SM-LP-5001 and SM-LP-5002 will be 2000 VRMS for one
minute. As noted, this DWV rating still exceeds the required DWV by 33 %.
Previously, SM-LP-5001 and SM-LP-5002 specifi ed a DWV of 4600 VRMS for one minute. There is
a decrease in DWV strength after soldering. The revised DWV of 2000 VRMS for one minute
accounts for this decrease after soldering
