Notes
• Consult factory for extended resistance range.
(1)
Power rating depends on the maximum temperature at the solder point, the component placement density and the substrate material.
(2)
Continuous working voltage shall be
P
x
R
or maximum working voltage, whichever is less.
(3)
MIL case size 0705 and EIA case size 0805 are dimensionally the same.
