This specification specifies the general requirements for film fixed resistor networks, film fixed resistors, and ceramic capacitor resistance capacitance networks. This specification applies to the fixed resistance networks of airtight and non airtight sealing membranes, as well as the resistance and capacitance networks of membrane fixed resistors and ceramic capacitors. These networks are composed of membrane fixed resistors or membrane fixed resistors and ceramic capacitors. This specification specifies two levels of products, one being highly reliable The "M" grade product selected for 100% power aging, and the other type is the "C" grade product selected for non power aging. The relevant clauses in the following documents become the clauses of this specification through reference. For dated or revised reference documents, any subsequent modification orders (excluding corrected content) Neither the revised version is applicable to this specification, but it is suggested that all parties using this specification explore the possibility of using its latest version. For referenced documents without date or revision, the latest version applies to this specification.
