WebKey Definitions: a) Creepage Distance: “Creepage D istance” is the shortest distance over surface between two conductive parts. For example, it is often necessary to measure the creepage distance between two traces across the surface of a printed circuit board. WebNominal creepage distance : 60 mm - 150 mm : 120 mm - 130 mm : 290mm - 1655mm : 440mm - 1100mm (Special executions with nominal creepage distance up to 1560 mm …
WebWhen it comes to high voltage safety certifications, the following three distances are of utmost importance to determine insulation ratings of semiconductor components: clearance, creepage, and DTI. Clearance is the shortest distance in air between two conductive parts and creepage is the shortest distance along the surface
