Description

The VHZ series of resistors is the hermetic version of the molded "Z" series devices. Hermetic sealing eliminatesthe ingress of both oxygen, which degrades resistors over long periods, and moisture which degrades resistors more quickly. These VHZ series 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.

In the VHZ series , VH102Z is the hermetically-sealed counterpart of the Z201 high-performance molded resistors. VHZ555 is the hermetically-sealed version of the Z555, MIL style RNC90Z.
