(g) 0.005 0.012 0.036 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) General Note Welwyn Components reserves the right to make changes in product specification without notice or liability.
