Construction
A resistor element is applied to an alumina substrate. The product is adjusted to
value and protected. Marking is applied to 0603 and 0805 sizes. A wraparound
conductor is applied to join the top and bottom sides. The terminations are
electroplated with a Ni barrier layer prior to plating with a Sn finish.
Solvent Resistance
The body protection and marking are resistant to all normal industrial solvents
suitable for printed circuits.
Flammability
The resistor will not burn or emit incandescent particles under any condition of
applied temperature or overload.
Solderability
95% min coverage (MIL-STD 202F / 208H, 235C 2 secs)
