Overview
IEC 62490-2:2010 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the Equivalent Series Inductance (ESL) measuring method for surface mount capacitors used in electronic equipment. This part of the IEC 62490 series focuses exclusively on the techniques required to accurately measure the ESL of surface mount capacitors with specific configurations, ensuring repeatability and reliability in electronic component testing and quality assurance.
This standard is essential for manufacturers, test engineers, and quality control professionals working with surface mount capacitors in applications where precise measurement of electrical characteristics like ESL is critical to overall circuit performance.
Key Topics
