KEMET Webinars

Calculating the operational life of capacitors seems like an easy task, but care must be taken when calculating their lifetime. How life is calculated depends on the operating conditions and the device type.

In this live webinar, Jekaterina Stael von Holstein, Field Application Engineer at KEMET, presents the methodologies for calculating life...

Würth Elektronik Webinar

If the power supply of the application breaks down, this is not a pleasant situation. Würth Elektronik eiSos built up a demonstration, which shows a hot swappable backup solution with a size of 10 cm x 18.5 cm (3.94 inch x 7.3 inch).

The input voltage is 24V and the backup...
