EN 60301:2012

Preferred diameters of wire terminations of capacitors and resistors

IEC 60301:2012 gives a series of preferred diameters of the finished wire terminations of capacitors and resistors for use in electronic equipment. This third edition cancels and replaces the second edition, published in 1971, and its Amendment 1, published in 1972, and constitutes a technical revision. The main technical changes with respect to the second edition are the following: - employment of SI units only in the normative part of this standard, causing transfer of all imperial dimensions from Table 1 to the informative Annex A, - addition of two smaller diameters of wire terminations in Table 1, and - tightening of the tolerance ranges defined by minimum and maximum diameters in Table 1.

Bevorzugte Durchmesser für Anschlussdrähte an Kondensatoren und Widerständen

Valeurs préférentielles des diamètres des fils de sorties des condensateurs et résistances

La CEI 60301:2012 donne une série de valeurs préférentielles pour les diamètres des fils de sorties finis des condensateurs et résistances destinés à être utilisés dans les équipements électroniques. Cette troisième édition annule et remplace la deuxième édition parue en 1971, ainsi que son Amendement 1, paru en 1972, et constitue une révision technique. Les modifications techniques principales par rapport à la deuxième édition sont les suivantes: - utilisation d'unités SI uniquement dans la partie normative de la présente norme, entraînant un déplacement de toutes les dimensions impériales du Tableau 1 à l'Annexe A, informative, - ajout de deux diamètres plus petits de fils de sorties dans le Tableau 1, et - abaissement des plages de tolérances définies par les diamètres minimal et maximal du Tableau 1.

This European Standard was approved by CENELEC on 2012-08-17. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the CEN-CENELEC Management Centre or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the CEN-CENELEC Management Centre has the same status as the official versions.
