BS EN 61021-1 is a British Standard for laminated core packages for transformers and inductors.
BS EN 61021-1 guideline specifies the dimensions, with their associated tolerances, of a range of laminated core packages using YEE 2 laminations, both in their standard configuration and for assemblies using two larger E parts.
Note: Laminated cores are normally constructed from laminations made from material of the composition corresponding to the designation C22, E1, E3, E4 or F1.
BS EN 61021-1 on laminated core packages for transformers and inductors is useful for:
The safety of electronic appliances during manufacturing is important and the process of defining the terms used brings uniformity and facilitates development in the industry. BS EN 61021-1 provides guidelines to manufacturers on how to use laminated core packages for transformers and inductors, core size, dimensions, and tolerances for adequate performance in that application.
When these laminated core packages for transformers and inductors are handled according to the standards provided in BS EN 61021-1, it ensures smooth workflow and safety.
