Rated DC Current (I sat): The current when the inductance becomes 30% typical its initial
value (Ta=25ºC)
252010, 252012, 252510, 322515(C)
Temperature Rise Current (I rms): The actual current when the temperature of coil
becomes
∆ T=40ºC
(Ta=25ºC)
Operating temperature range: -40 ~ 105ºC
Rated DC Current: The current when the inductance becomes 10% lower than its initial
value or the current when the temperature of coil increases
∆T20ºC.
The smaller one is
defined as Rated DC Current. (Ta=25ºC)
