*A Saturation Current : This indicates the value of D.C. current when the inductance decreases to 65% of it's nominal. ( ) typical value.
*B Saturation Rated Current : The current when the inductance becomes 35% lower than its nominal value.(Ta=20°C)
*C Saturation Rated Current : The current when the inductance becomes 25% lower than its nominal value.(Ta=20 °C)
*D Temperature Rise Current : The actual current when temperature of coil becomes
T=40°C. (Ta=20°C)
