The terminations are electroplated with a Ni barrier layer prior to plating with Pd/Ag terminations are applied to the top and bottom of an alumina substrate. A resistive element is printed between the top face conductors, a Sn finish. 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 Marking a Sn finish. Where space allows, LHVC resistors are marked with value in three or four characters. The coding is two digits for E24 or three digits for E96 fol- lowed by one multiplier expressing the number of zeros. For E96 values on LHVC0603 standard EIA-96 codes are used, consisting of a 2 digit value Marking code and one letter multiplier code.
