Ohmcraft HVD30 Series

Ohmcraft HVD30 Series

The HVD30 through-hole high voltage divider resistor series from Ohmcraft® offers a voltage rating of 30kV, power rating of 3W, standard ratios of 1000:1 (A) or 100:1 (B) and a resistance range from 100kΩ up to 1TΩ all in a small radial leaded through-hole package. By utilising their patented Micropen® precision printing technology, they are able to provide a superior precision, thick-film through-hole resistor. HVD30 high voltage divider resistors offer very low noise, ultra-high stability with ratio tolerances down to ±0.1% (between 100kΩ and 100MΩ), absolute TCR as low as ±25 ppm/°C (between 1MΩ and 500MΩ) and VCR down to 0.05 ppm/V.

  • Ratios of 1000:1 (A) and 100:1 (B) as standard or custom ratios available upon request
  • Available in any resistance between 100kΩ and 1TΩ
  • Utilises patented Micropen® precision printing technology
  • Ultra-high stability
  • Very low noise
  • Ratio tolerance as low as ±0.1% (between 100kΩ and 100MΩ)
  • TCR as low as ±25 ppm/°C (from +25°C up to +75°C, between 1MΩ and 500MΩ)
  • Maximum voltage rating of 30kV
  • Maximum power rating of 3W
  • Working temperature from -55°C up to +150°C

Ohmcraft's HVD30 high voltage dividers are available with various options including the following lead styles:

  • T - 100% Tin spade leads (RoHS Compliant)
  • S - Tin Lead (Sn60Pb40) solder spade leads (Not RoHS Compliant)
  • W - 100% Tin 22AWG wire leads (RoHS Compliant)
  • B - Tin Lead (Sn60Pb40) solder 22AWG wire leads (Not RoHS Compliant)

As well as the above lead styles, the HVD30 series is available with various coatings including the following:

  • 2 - Bare resistor element
  • 3 - Powder Coating
  • 4 - Single surface epoxy

The HVD series divider ratio is calculated using the formula Ratio = (R1+R2)/R2. Resistance in the part number is the total resistance i.e. R1 + R2.
