That would cause the emission of white phosphorus vapour, which burns in
air spontaneously even at room temperature, and is highly toxic. That
is, if there is any red phosphorus there, which I very much doubt.

Hi Christopher:
To put your mind at ease regarding the flammability of the Red
Phosphorus, I suggest you test it. 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.
Good luck, and best regards,
Rich

*Subject:* [PSES] Using Red Phosphorous ferrite core on a 48VDC motor
Folks,
I need some help to answer this product safety question.
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
