This Würth Elektronik webinar discuss how to efficiently connect filter components and minimize parasitic to address EMC concerns. The video shows impact of PCB layout designs in practical application examples and LTSpice simulation.
The component density in modern designs is becoming ever greater. From an EMC point of view, many PCB layout designs today are therefore created as multilayer designs with separate layers for the supply of the components.
These questions will be investigated by means of various measurements and LTSpice simulations:
- How many vias are actually useful and what arrangement should be chosen for them?
- How much does the capacitance value and the impedance of the ferrite change with voltage and current and what does this mean for my filter characteristic?
