16、 EI:C0023 7 INTRODUCTION The first edition of IEC 60862-3 (1986) contained 13 SAW filter enclosure types showing the dimensional and geometrical characteristics of these enclosures. Since its release, due to progress in technology, many of the enclosures given in that standard have become obsolete.
17、Bearing this in mind, TC 49 has issued a questionnaire on all outlines contained in IEC 60862-3. Based on the replies received, TC 49 made a decision at the meeting held in Rotterdam in June 1996 to retain only enclosures which remained in “wide usage” at that time. These enclosures are specified in
18、 the present standard. The following 5 enclosure types have been deleted from the first edition of IEC 60862-3 (1986): SFA 02, SFB 01, SFB 02, SFC 01, SFD 01.

19、IEC 60862 specifies the outline drawings for surface acoustic wave (SAW) filters with leaded enclosures. 2 Guidance for the standardization of outline drawings for frequency control and selection devices In order to achieve a uniform presentation of all outline drawings for frequency control and sel
20、ection devices the following guide should be considered: 2.1 An outline drawing should show all dimensional and geometrical characteristics of an enclosure necessary to ensure mechanical interchangeability with all other enclosures of the same outline. Enlarged detail view may be used, if necessary.
21、 2.2 The outline drawing should consist of three parts: 2.2.1 A drawing with dimensional symbols (capital letters) as shown in Figure 1 below with applicable notes, if necessary. 2.2.2 A tabular listing relating the drawing symbols to the actual dimensions. Where possible this should be shown on the
22、 same page as the drawing. 2.2.3 An “actual-size” sketch (scale 1:1). 2.3 The outline drawing should be executed in the third angle projection. 2.4 The function and identification of the lead connections (termination) should be determined by agreement between the supplier and user. They should not b

24、 (termination) cross-sectional dimensions should be listed with minimum and maximum values. If applicable, nominal dimensions may be added. 2.9 The spacing of the leads (terminations) symbol H should be listed with minimum, maximum and nominal dimensions.
