Foreword This document (EN 140402-801:2015) has been prepared by CLC/TC 40XB "Resistors". The following dates are fixed:
• latest date by which this document has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2015-12-15 • latest date by which the national standards conflicting with this document have to be withdrawn (dow) 2017-12-15
This European Standard supersedes EN 140402-801:2005. Preceding document on the subject covered by this specification has been: – CECC 40 402-801:2000-02. EN 140402-801:2015 includes the following significant technical changes with respect to EN 140402-801:2005: – adoption of P70 as the rated dissipation, leaving the prior used P25 as an additional information; – for style RW1607M, increase of P70 to 2,4 W, with P25 = 3,0 W; – introduction of a test on the resistance to electrostatic discharge (ESD) in 1.7 and Annex A; – introduction of code letters for the temperature coefficient (TCR) as in EN 60062:2005; – revision of ordering information in 1.10.4; – adoption of the IECQ rules of procedure according to QC 001002-3:2005; – revision of the sample quantities and the sequence of tests in Annex A; – editorial revision. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights. This specification is part of a series of documents describing fixed low power wire wound surface mount (SMD) resistors as follows: – EN 60115-1, Fixed resistors for use in electronic equipment — Part 1: Generic specification (IEC 60115-1, modified) – EN 60115-8, Fixed resistors for use in electronic equipment — Part 8: Sectional specification — Fixed surface mount resistors (IEC 60116-8, modified) – This detail specification.
