Hello Team,
My customer is going to use our ISO7741 DBQ package.
Then engineer wants to make sure that our CTI can be certified by UL.
They need creepage distance is more than 3mm with CTI>600V.
Our data sheet shows CTI>600V with test condition DIN EN 60112 (VDE 0303-11); IEC 60112
Does it mean that CTI can be certified by UL ?
If it s not certified by UL, it may be recognized as material group III (lowest) and needs wider distance on the design.
Any advice will be appreciated.
