Characteristics
for 252010E / 252012E / 252510 / 322515C
– Rated DC Current(I sat): The current when the inductance becomes 30% typical its initial value (Ta=25°C)
– Temperature Rise Current(I rms): The actual current when the temperature of coil becomes ΔT40°C. (Ta=25°C)
– Operating temperature range: -40 ~ 125°C
except 252010E / 252012E / 252510 / 322515C
– Rated DC Current: The current when the inductance becomes 10% lower than its initial value or the current when the temperature of coil increases ΔT20°C. The smaller one is defined as Rated DC Current. (Ta=25°C)
– Operating temperature range: -40 ~ 125°C
