• Measuring Frequency (L) : 100KHz
• Tolerance of Inductance: 20%(M)
• Rated D.C Current (SCMD4D06/4D08/4D11/4D13/5D11)
This indicates the value of current when the inductance is 10% lower than its initial value at D.C superposition or D.C current when at t=40ºC whichever is lower.
• Rated D.C Current (SCMD5D13)
This indicates the value of current when the inductance is 65% more than its nominal value and the temperature is rising at t=40ºC lower at D.C superposition.
