Features
1. Resistors that can work in a continuous high-voltage environment are generally encapsulated in transformer oil or epoxy resin for use.
2. Power rating: 1/4W-30W
3. It is non-inductive, resistant to high voltage, small size and high power, long life, good moisture resistance, and stable electrical performance.
4. The lead-out end adopts lead-in type lead-out
Structure
1. Using the screen printing method, the printed layer is a resistive film with a thickness of tens of microns, which is sintered at a high temperature. The matrix is 96% aluminum oxide ceramics, which has good thermal conductivity and high mechanical strength. The resistive film layer adopts noble metal ruthenium-based slurry, and the electrical performance is stable.
2. The process flow is generally electrode printing→electrode sintering→resistance printing→resistance sintering→dielectric printing→dielectric sintering, and then through the processes of resistance adjustment, welding, and encapsulation.
Applications
1.High-voltage power equipment, medical CT and X-ray machines, high-voltage test equipment, high-voltage power supplies, vacuum equipment, high-voltage inverters, voltage dividers, high-voltage circuits, capacitor discharge circuits, high-voltage buffer circuits, environmental protection equipment, electrostatic dust removal equipment, Power system, high voltage instrumentation, pulse modulator, imaging equipment, impulse voltage generator, etc.
2.Where high voltage or pulse is used, high voltage resistors are suitable
