HIGH VOLTAGE AND HIGH VALUE RESISTORS UHV SERIES Term.W is RoHS compliant & 260°C compatible RoHS Resistance values up to 200TΩ (2x1014Ω), tolerances to 1%! Voltage rating to 14KV. Pulse voltage to 50KV avail. Low noise & voltage coefficient Industry’s best TCR, as low as ±25ppm/°C SPECIAL MODIFICATIONS Screw terminations available Resistance tolerances to ±0.2%, matching to 0.1% Voltage or resistance ratios up to 1000 : 1±1.0% Increased power, voltage, and operating frequency levels World’s highest resistance range! 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. |← ←1.25 [32] Min.*→| ← DERATING L → →| *UHV3=1 [25.4] Min. 100 % OF RATED POWER RESISTORSCAPACITORSCOILSDELAY LINES 80 ↓D ↑ .041 [1.04] Max. ↓ ↑ UHV1 & 2 60 40 UHV3 20 0 20 RCD TYPE 40 60 80 100 AMBIENT TEMPERATURE (°C) Wattage @ 25°C Working Voltage* UHV1 1.0W 4000V UHV2 2.0W 14,000V UHV3 1.0W 1000V 120 140 Avail.

Noise (per freq. decade, typ.) 1 Characteristics are typical for resistance range up to 1GΩ , consult factory concerning higher values 2 Measured between 100V and 500V on values above 100M (tighter VC’s available) RESISTANCE CODE 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.
