scope:

1.1 This specification covers the requirements to which the specified grades of soft magnetic manganese zinc (MnZn) ferrite materials shall conform. Cores made from these materials are used primarily in transformers and inductors.

1.2 Frequency-MnZn ferrite cores are primarily used for frequencies in the range of 10 kHz to 1 MHz. Many inductors have a DC component as well.

1.3 Magnetic Flux Density-Applications consist of two main categories, high and low magnetic flux density.

1.3.1 High Magnetic Flux Density-Transformers used for power conversion. Inductors or chokes used in high current applications.

1.3.2 Low Magnetic Flux Density-Transformers, inductors, chokes used for signal conditioning.

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units, which are provided for information only and are not considered standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
