Construction  
Marking  
Termination conductors and ruthenium oxide resistive material  
are printed in a non-inductive pattern onto the surface of a 96%  
alumina substrate. A screen-printed protection is then applied  
and terminal wires are then attached.  
Type reference, resistance value and tolerance are legend  
marked. The resistance value code conforms to IEC 62.  
Solvent Resistance  
The body protection and marking are resistant to all normal  
industrial cleaning solvents suitable for printed circuits.  
Terminations  
The termination wires are tin coated copper.

Application Notes  
Due to the high voltage, which can appear between the terminations and any adjacent metal part, resistors should be mounted at  
an adequate distance from other conductors.  
For some ultra-high voltage applications it is required to immerse the components in oil or SF gas or pot them in void-free silicone  
6
compound to reduce corona or surface tracking. The printed protection is suitable for these applications.  
The divider consists of high value R 1 and low value R 2. The voltage division ratio of the divider is given by R atio = R 2 / (R 1 + R 2).  
Ordering Procedure  
E xample: PHVD15 for a voltage ratio of 1:1000, with R 1 = 99.9 megohms and R 2 = 100 kilohms (total R 1 + R 2 = 100 megohms)
