Cylindrical Thick Film Non-Inductive High Voltage Resistor
Product Overview
This cylindrical thick-film non-inductive high-voltage resistor is manufactured using advanced thick-film technology, exhibiting excellent high-voltage resistance, stability, and reliability. Its main substrate is bauxite ceramic (Al₂O₃) with a purity exceeding 95%, and the resistive film is made from a composite paste composed of precious metals such as silver, ruthenium, and palladium, sintered at 850℃ to ensure superior thermal conductivity and electrical performance.
This resistor is available in both silicone and glass encapsulation, enabling stable operation in environments such as air, high-pressure oil, and epoxy resin. Its small size and high power density make it suitable for various high-voltage pulse and voltage regulation systems, meeting the demanding requirements of industrial and medical applications.
