Hi!
How do I calculate the saturation current of this P-core:
l_e=25.9 mm mu_e=192
Ferrite N48
B*2*pi*r=mu*N*I
So I assume substituting 2*pi*r with the core length will work aproximately with a P-core, I do:
NI=B_S*l_e/mu = 0.42 mT * 0.0259 m / (192 * 4E-7 * pi) = 45 A
I don't believe 45 A. I have a 26/16 P-core (without specs, 26 mm diameter, 16 mm high (per set with 2 halves)) with saturation current of
3.5 A. Even though the P1811 has 0.1 mm gap 45 A seem too large.I want to know this before I buy the core.
Thanks, Bernhard
