DIN EN 60679-3
Quartz crystal controlled oscillators of assessed quality - Part 3: Standard outlines and lead connections (IEC 60679-3:2012); German version EN 60679-3:2013

Title (German)

Quarzoszillatoren mit bewerteter Qualität - Teil 3: Norm-Gehäusemaße und Anschlussdrähte (IEC 60679-3:2012); Deutsche Fassung EN 60679-3:2013

Overview

This part of IEC 60679 specifies the outline dimensions and lead connections for quartz crystal controlled oscillators with lead enclosures. In order to achieve a uniform presentation of outline drawings for frequency control and selection devices, the following shall be considered: - an outline drawing shall show all dimensional and geometrical characteristics of an enclosure necessary to ensure mechanical interchangeability with all other enclosures of the same outline. Enlarged and detailed view may be used, if necessary. - The outline drawing shall consist of a drawing with dimensional symbols (capital letter), a tabular listing relating to the drawing symbol to the actual dimensions; where possible, this shall be shown on the same page as the drawing; and an "actual-size" sketch (scale 1:1). - The outline drawing shall be executed in the third-angle projection. - The function and identification of the lead connections (termination) shall be determined by agreement between the supplier and user. They shall not be defined on the outline drawing. - Descriptive footnotes may be used at the bottom of/ or adjacent to, the drawing with proper reference to the body of the drawing. - All dimensions shall be in millimetres (mm). - Outline dimensions A, B, C, D and E shall be listed with maximum values only. - If there are plural identical enclosures with different height ©, C shall be expressed with a suffix number. The following letter and number after the basic type number (four digits) indicate the enclosure height and lead length. The identity references are given in the table in the sheet. - Lead (termination) cross-sectional dimensions shall be listed with minimum and maximum values. If applicable, nominal dimensions may be added. - The spacing of the leads (termination) - symbol H - shall be listed with minimum, nominal and maximum dimensions. This edition includes the following significant technical changes with respect to the previous edition DIN EN 60679-3:2002-7: - CO 01, CO 07, CO 10, CO 17 and CO 18 were deleted; - The current pin layout of CO 06 was deleted. And new pin layout of CO 06 was added as CO 40; - New layout of CO 15 was added as CO 41; - Two new enclosures, CO 42 and CO 43 were added. The responsible committee is DKE/K 642 "Piezoelektrische Bauteile zur Frequenzstabilisierung" ("Piezoelectric devices for frequency control and selection ") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
