Hi Christopher. It may not specifically apply to a ferrite core, but here is another thing to watch out for with Red Phosphorous: https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1598224

Suspend the core by a wire. Apply a small flame (1 inch max) from a barbecue starter to the bottom of the core, and see what happens. The core should provide a heat sink for the red phosphorus such that it cannot reach ignition temperature, or exceed the burn time of 94V-0. I agree with Ted and Ralph.

We are using ferrite core T60006-L2025-W380 to supress radiated emissions on the 48VDC motor cable. I am concerned about the flamilibility of the Red Phosphorus which is contained in the Ferrite core. Any help is appreceiated Christopher Nextracker LLC. ________________________________ This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
