What is BS EN 61605 - Marking codes for fixed inductors about?
BS EN 61605 is a European standard that specifies marking codes for fixed inductors.
BS EN 61605 specifies the following marking codes for fixed inductors.
- The code specified in Clause 4 gives a system for marking inductance values by means of digits and letters.
- The code specified in Clause 5 gives a system for marking the tolerance on inductance values by means of letters.
- The code specified in Clause 6 gives a system for marking date codes on fixed inductors by means of letters and digits.
Who is BS EN 61605- Marking codes for fixed inductors for?
BS EN 61605 on marking codes is relevant to:
- Fixed inductor manufacturers and suppliers
- Electronic and telecommunication equipment manufacturers and suppliers
- Retailers
- Product designers
- Electrical engineers
Why should you use BS EN 61605 - Marking codes for fixed inductors?
Marking codes act as a tool for easy identification of the properties and characteristics of products, assisting entities across the supply chain with necessary and required information. These codes also play a significant role in warehousing processes and product tracking. In this regard, choosing the wrong marking and coding could negatively impact your production line.
BS EN 61605 specifies colour codes for fixed inductors that consist of four bands, of which the first three bands indicate inductance values and the fourth band indicates tolerances.
BS EN 61605 provides digits with letter codes for inductance values, letter codes for tolerances of inductance values and date code system for fixed inductors.
By adopting these standardized marking codes for fixed inductors, entities across the supply chain can be rest assured of its traceability, authenticity and compliance with best industry practices.
What’s changed since the last update?
BS EN 61605:2017 and replaces the first edition published in 2003. This edition constitutes a minor technical revision:
- The date code system for fixed inductors has been updated.
