※1 Measured frequency L
1.2μH ~ 7.6μH ; at 100 kHz
10 μH ~ 1 mH ; at 1 kHz
※2 Saturation current: This indicates the value of D.C. current when the inductance becomes 25% lower than it’s initial
value. (Ta=20℃)
※3 Temperature rise current : The actual value of D.C. current when the temperature of coil becomes △T=40℃ (Ta=20℃).
