RI80 High Frequency Glazed Non-inductive High Voltage Resistor

Product DescriptionHigh Frequency Glazed Non-inductive High Voltage Resistor
Features
1. The RI series resistors use a ceramic containing more than 95 aluminum as a resistor base, and a noble metal silver palladium, rhodium, ruthenium and other metal oxides (palladium oxide, ruthenium oxide
Etc.) and glass glaze adhesives are mixed into a slurry material and a serpentine pattern design process, the resistive film is printed on a ceramic substrate, and sintered at a high temperature.
High stability, small temperature coefficient, accurate precision, high voltage resistance. This kind of resistor is also called thick film resistor.
2. The lead ends are welded and assembled with copper caps or lead pins, pressed into both ends of the resistor ceramic rods and processed into resistors to provide a firm terminal connection.
3. The surface of the resistor is coated with green or red high-voltage insulating heat-dissipating paint, which is baked at a high temperature after being dried naturally.
4. Resistance power from 1W-500W, working voltage from 10KV-100KV, high resistance range, from 1K-1000KM, according to customer to provide a variety of resistance, electrode endMouth and special resistance.
5. Absorbs a large amount of energy in a high pressure environment while maintaining a non-inductive/low-sense and heavy-negative characteristic. It can provide customer-defined design and close tolerances
6. Small size, stable performance, accurate precision, high voltage resistance.Rated Power: 5W 8W 10W 15W 20W 30W 50W 80W 100W 150W 200W 300W 400W 500W
