SMD (surface mount inductors)

Surface mount inductors manufactured in DuraFlux™ materials offer low profile, small sized, high energy core solutions for today's power hungry applications. Using flat wound coils allows for extreme currents typically found in today's modern notebook processors and similar small sized electronic devices. The high dc biasing ability of DuraFlux™ materials allows for a minimum drop off in inductance while still maintaining a high level of efficiency.

 

SMD cores are assembled with an ER and I core. The I core forms the base of the inductor where the coil winding is terminated. The unique design of the core reduces any flux leakage to a minimum while still maintaining maximum heat dissipation from the core surface.

 

Two standard footprint sizes are available in 12.7 x 12.7mm and  6.6 x 6.6mm. I cores are available in two standard shapes notably "H" or "T" configurations. DuraFlux™ materials are blended to provide permeability ranges from 32µi to 60µi. Note: SMD cores are made to meet specific inductances adjustable by core height and material permeability.
