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.

PERFORMANCE CHARACTERISTICS 1
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.
UHV1&2 = -55°C to +150°C
UHV3 = -40°C to +100°C

Voltage Coefficient 2
10 to 80ppm UHV3
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.
