13、, (c) BSIEN 61837-2:2011 - 2 - Foreword The text of document 49/884/CDV, future edition 2 of IEC 61837-2, prepared by IEC TC 49, Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control, selection and detection, was submitted to the IEC-CENELEC parallel vote
14、 and was approved by CENELEC as EN 61837-2 on 2011-07-01. This European Standard supersedes EN 61837-2:2000. In EN 61837-2:2011, types of enclosures are renamed to express their features in their names for better understanding. The relative comparison of new types with old ones is listed in Table. 1
15、. New names of enclosures express configuration type, terminal lead numbers, sizes and arrangement of terminal pads. The details of definition are shown in Clause 3: Configuration of enclosures, and Clause 4: Designation of types. Enclosures in EN 61837-2:2011 are based on EN 61240. In EN 61837-2:20
16、11, 27 enclosures are added to EN 61837-2:2000, as follows: QCC-12/1407A, DCC-2/1206A, QCC-10/9272A, DCC-4/9070A, DCC-2-8045B, DCC-6/7834B, DCC-6/7050A, QCC-10/7050A, DCC-4/6035C, DCC-2/6035C, QCC-8/5045A, DCC-4/5032A, DCC-4/5032C, DCC-2/4818C, DCC-2/4115C, QCC-8/3838A, DCC-6/3838A, DCC-4/3225C, DCC
