Leakage Current

The leakage current is an electric current flowing in an undesirable current path.
In EMC filters this is done by the applied Y-capacitors, which are used for noise suppression. Information on the amount and classification of leakage currents are explained in detail and are listed in the data sheets.

MTBF

The term MTBF is the English acronym Mean Time Between Failure and describes reliability of a component. The operating time of a system can be calculated based on thementioned value of the component. - The higher this value, the more reliable the component.
