Measuring frequency (L)：1.0μH - 7.4μH (100kHz), 10μH – 1.0mH (1kHz)
※2
Saturation current: This indicates the actual value of D.C. current when the inductance becomes 25%lower than its initial value.
※3
Temperature rise current: The actualvalue of D.C, current when the temperature of coil becomes
⊿T=40℃.
