High performance metal oxide resistor

Product introduction:

Metal oxide resistor is a semiconductor ceramic element made of zinc oxide as the main raw material, and its resistance value changes nonlinear with the change of applied voltage. Metal oxide resistor is mainly used to assemble various types and grades of lightning arrester, is the core component of metal oxide lightning arrester, its quality directly determines the performance of lightning arrester.

The new version of the national standard GB/T 11032-2020 has been officially implemented on July 1, 2021, the new version of the national standard puts forward higher requirements for the performance of metal oxide resistance pieces, introduces the new concept of "repeated transfer charge", and evaluates the performance of all resistance pieces with repeated transfer charge ability, and Qrs has become a key performance indicator of resistance pieces. In order to make the products fully meet the requirements of the new national standards, the company's technology research and development team has developed a new formula and process through unremitting efforts for the production of new metal oxide resistor, which is named "high performance metal oxide resistor".

The high-performance metal oxide resistor produced by our company has the key characteristics of strong charge transfer ability, low reference voltage change rate after current shock resistance, good long-term stability, etc. The whole series of high-performance metal oxide resistor has passed the performance test of the "National Electrical Products Quality Supervision and Inspection Center" (Suzhou Institute of Electrical Science and Technology). We have prepared for the production and supply of metal oxide resistor to our customers according to the new national standard, welcome customers to choose this series of products!
