Construction
Pd/Ag terminations are applied to the top and bottom of an alumina
substrate. A resistive element is printed between the top face
conductors, which is then adjusted to value and protected.
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)
