WebJan 31, 2024 · Creepage refers to the shortest distance along the surface of an insulator. Clearance measures that distance through the air. Creepage can also take short circuits into account for gaps and grooves across surfaces, where the air has less resistance. The repercussions of violating minimum distances can be extremely expensive.

WebJun 28, 2024 · Creepage is the path-dependent sibling of clearance. In the transportation metaphor, creepage would act equivalent to a train (or car, or boat) in that, by design, it has to travel along the surface of the medium. At a minimum, this means creepage must be as long as clearance, but never shorter. WebJan 29, 2015 · 1.

Clearance Distance Data as per UL-60950/IEC-60950

WebClearance is the shortest distance in air between two conductive parts, whereas creepage is the shortest distance along the surface of an insulator between two parts. The minimum distance is defined to ensure that the voltage differences won’t cause breakdown. Contaminants, whether in the air or settled on a PCB often call for wider separation. WebFeb 26, 2024 · These separation distances are known commonly as creepage and clearance distances. Creepage is the shortest distance between two conductors as measured across the surface of a dielectric material. Clearance is the shortest distance between two conductors as measured through air.
