Kool Mu Inductors for DC and SMPS applications.

Kool Mu inductors have lower losses and pack more energy per volume than regular iron powder inductors, and cost less than MPP inductors. As such they have found wide application in quality affordable products in recent years.Furthermore, the AC inductance is far more stable and changes much less with applied AC current than that of the corresponding iron powder cores.

These are specially wound using the latest state of the art equipment and winding techniques to yield very high frequency responses, making them suitable for use at frequencies from 100kHz to 100MHz.

Rated DC current is that at which the temperature rise is approx. 30°C.
A ripple current 10% that of the DC current is assumed.
Inductances are series inductances.
DCR values are at 20°C.
