Hi Mal,
the Philips data sheet says:
3C85 SPECIFICATIONS
SYMBOL CONDITIONS VALUE UNIT
ui 25 °C; <10 kHz; 0.1 mT 2000 ±20%
ua 100 °C; 25 kHz; 200 mT 5500 ±25%
B 25°C; 10 kHz; 250 A/m >400 mT
100 °C; 10 kHz; 250 A/m >330
Pv 100 °C; 25 kHz; 200 mT <140 kW/m^3
100 °C; 100 kHz; 100 mT <165
rho DC; 25 °C approx. 2 ohm m
Tc >200 °C
density approx. 4800 kg/m^3
Note that the (initial) permeability goes
from 1700 to 4000 in the range from 0°C to 100°C...

Hi All
Does anyone know the permability and spec of 3c85 material? I cannot find
this info in any of my tech info books.
The T200 series seem very low like u10 powdered iron whereas the 3c5 ferrite
type are as high as u7000
Seems important to get the right mix
