INTRODUCTION
The “VH” series of resistors is the hermetic version of
several molded “S” series devices. Hermetic sealing
eliminates the ingress of both oxygen, which degrades
resistors over long periods, and moisture which degrades
resistors more quickly. These parts are made with glass
to metal seal enclosures employing Kovar eyelets which
allow the copper leads to pass through the enclosure to
minimize the thermal EMF from the lead junctions. Rubber
fill between the metal housing and resistance element
acts both as a mechanical damper and thermal transfer
path.
VHS102 and VH102K are the hermetically-sealed
counterpart of the S102C and S102K high-performance
molded resistors. VHS555 is the hermetically-sealed
version of the S555, MIL style RNC90Y.
