White Paper: Lightning Surge and AC Power Cross Protection for PoE Applications

Sponsored by: Bourns

A new Bourns application note presents a very robust lightning protection circuit for PoE applications. This valuable design resource highlights a new solution where the protection circuit is capable of withstanding severe lightning surges such as 4 kV 10/700 μs voltage surges per ITU-T K.44. It also includes how to implement effective AC power cross protection and demonstrates how this solution has minimal impact on signal integrity in low voltage, high-speed communication circuits.
