Dimensional tolerances of ferrite cores not-eligible the ultrasonic method only permits

the ultrasonic method only permits a qualitative evaluation of the bonding and not a quantitative determination of the bond strength

but in recent years

but rather identifies generic processes applicable to all these incidents

Higher voltages are allowed at the discretion of the manufacturer provided the insulation is not damaged due to overstress by the voltage applied

servicing and after repair

Dimensional tolerances of ferrite cores not-eligible the ultrasonic method only permitsWhat is PD IEC TR 63090 Dimensional tolerances of ferrite cores about? PD IEC TR 63090 is a document that discusses dimensional tolerances of ferrite cores, as a result of which manufacturers and suppliers can ensure their products are fit for purpose. PD IEC TR 63090 gives guidelines on the dimensional tolerances of ferrite cores that are generally used by ferrite core suppliers. As a reference, this is useful for ferrite core suppliers and users
