1) The given value is considered an example based on pollution degree 2.

2) After stress test according to qualification plan.

3) Not subject to production test. Verified by design and characterization.

4) Agency type tested for 60 seconds by UL according to UL 1577 standard.

TLE4971 characteristics are tested at VDE according basic isolation as well and a report is available on request.
