RCD Type UHV resistors are suited for all high value applications
from general purpose bleed chains to highest reliability X-ray
systems and TWT amplifiers. RCD’s exclusive complex oxide
film features state-of-the-art performance and extended life
stability. The unique molecular structure of the resistive element
offers exceptional insensitivity to high voltage and thermal shock.
The protective insulation provides a high dielectric voltage, and
insulation resistance. Series UHV3 is hermetically sealed in a
glass or ceramic case, minimizing the effects of moisture or
contamination.

APPLICATION NOTES
1) Due to possible surface condensation, high voltages should not
be applied in conditions of high humidity. The end caps of UHV1&2
are uninsulated and need to be mounted an adequate distance
from conductors to ensure adequate isolation voltage.
2) Type UHV3 is coated with silicone to reduce condensation on the
glass case and minimize shunt resistance. The coating must not be
damaged or subjected to solvents; handle by terminations. UHV3
>100G are supplied with a guard band to minimize leakage current.
3) Resistance measurements on values over 1 Meg are made at 100V.
4) Resistors are available with screw terminations & tapped end caps to
provide virtually any voltage or resistance value by combining in series.
