This part of IEC 61248 specifies how to prepare detail specifications for high-frequency inductors and intermediate frequency transformers between 10 kHz and 2 GHz for use in electronic and telecommunication equipment to be released under the terms of IEC 61248-1 (QC 260000) capability approval. It includes a blank detail specification (BDS), which shows the format and indicates which tests are considered to be appropriate to this type of component, although the final selection of tests to be included in the inspection schedule is at the discretion of the specification writer. It also lists appropriate ratings and characteristics. The components covered by this part of IEC 61248 are essentially concerned with highfrequency inductors and intermediate frequency transformers of signals which are mainly used for electronic equipment.
