PRODUCT OVERVIEW
The 3500 series is a range of flat-coil power
inductors. They are ideal for high power designs
which demand reliability in high temperature
environments. Used to provide filtering or energy
storage, they are suited to many power applications
including portable devices, computers and telecom
equipment.
