Advance Technique of Non-Inductive & Serpentine Pattern (HI83)
Non-Inductive Performance:
- HI83 Non-Inductive Design which uses a serpentine resistive pattern that offers for zigzagging lines to carry current in opposite directions,
thereby achieving maximum neutralization of flux fields over the entire length of the resistor.
- This efficient non-inductive construction without derating of any performance advantages is ideal for applications where high frequency is required.
Serpentine Pattern Screen Printing Design:
- Type High Voltage HI83 Precision Resistors combine DeMint's Non-Inductive serpentine pattern, high thru-put screen printed silicone coating.
- The alignment of the gap in the serpentine resistor pattern with the gap in the coating pattern provides a complete encapsulation of the resistor element.
- The cap and lead assemblies are pressed onto the resistor core, finishing the resistor and providing rugged terminal attachment.
High Voltage Divider Application Notes (HI83)
- Due to the high voltage that may occur between the terminals and any adjacent metal parts,
the voltage divider should be installed at a sufficient distance from other conductors. - For some ultra-high voltage applications, it is necessary to immerse the component in oil or SF6 gas
or place it in a void-free silicone compound to reduce surface tracking or corona.
The printed protection is right for these applications. - The planar voltage divider consists of high value R1 and low value R2.
The voltage division ratio of the divider is specified by Ratio R2: (R1 + R2).
Example :
- HI83-20 for a voltage ratio of 1:1000, with R1 = 99.9 megohms and R2 = 100 kilohms (total R1 + R2 = 100 megohms) at 50ppm/°C absolute and 25ppm/°C tracking TCR, 1% absolute and 0.5% ratio tolerance.
