21、D MEASURING METHODS Part 1: Fixed, surface mounted inductors for use in electronic and telecommunication equipment 1 Scope and object This part of IEC 62025 applies to fixed, surface mounted inductors and ferrite beads. Should conflict arise between these specifications and the detail specifications

22、, the latter will take precedence. The object of this standard is to establish requirements for fixed, surface mounted inductors, to describe terms, to give recommendations for standard values and dimensions and to give guidance on fixed, surface mounted inductors. 2 Normative references The followi

23、ng referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 61605: 2005, Fixed inductors for use in electronic and t

26、(or H). As for the dimensions of shape D, the first two digits indicate the longer side dimension L, and the last two digits indicate the shorter side dimension W, as shown in Figure 1. As for the dimensions of shape K, the first two digits indicate the outline dimension L, and the last two digits i

46、tion is subject to agreement between supplier and user. In lieu of such an agreement, the marking information should be as published in the suppliers data sheet. One or more of the following types of marking information is recommended on the body or the package: a) user part number; b) serial number

47、, lot code or date code; c) characteristics as specified in IEC 61605; d) supplier part number and logo or mark; e) quantity (package only). 8 Direction marking or shape of polarity For the purpose of indicating the winding start location, or the first pin number, or first electrode, either a mark o

48、r a shape should be used. A shape indicator is a corner cut, or small circle indent, or other molded feature that indicates polarity on the inductor (if such indication is necessary).
