NOTES:
1.
Marked with: specific model ordered, date
code, job code.
2.
MATERIAL: Units are encapsulated in a low
thermal resistance molding compound which has
excellent chemical resistance and electrical
properties in high humidity environments and
over a wide operating temperature range. The
encapsulant and outer shell of the unit have
UL94V-0 ratings. Lead material is solder plated
to allow ease of solderability.
3. IMPORTANT:
When utilizing the PEM nuts for
board mounting, it is required to follow guidelines
in application note DCAN-40 available on the
web at www.cdpowerelectronics.com.
