ferrite core smd power inductor for Portable Communication Equipments
Description:
The inductance in general electronic circuit is hollow coil, or coil with magnetic core, can only pass small current, bear lower voltage;And the power inductance also has hollow coil, also has the core, the main characteristic is to use the thick wire to wrap, can endure dozens of Ann, hundreds, thousands, even tens of thousands of Ann.
E General information:
It is recommended that the temperature of the part does not exceed
125°C under
worst case operating conditions.
