Type HMG Series
The Tyco type HMG is suited to
applications requiring small size,
high voltage, high impedance and high
stability. Consistent quality and
reliability is achieved via a metal film
deposition on a high purity ceramic
core. Multi layer epoxy coating offers
excellent environmental protection. The
HMG Series is attractively priced and
particularly well suited to use as
voltage dividers, in X ray equipment,
and in high voltage power supplies.
