How to choose patch power inductor in circuit?

The customer service staff of Jinlai Electronics often receive the problem of choosing patch power inductor recommended by customers. How to choose the patch power inductor can be distinguished as follows:

1, power supply filtering, decoupling -I-shaped inductor

2. Switching power supply choke manganese zinc and powder core. -Alloy power inductor.

3.EMI shielding inductance, high permeability, nickel-zinc inductance.

4, low frequency-silicon steel sheet, powder core, alloy, manganese zinc ferrite and other inductors.

5. Intermediate frequency Mn-Zn and Ni-Zn ferrite inductors

6, high frequency-high Q value, no core inductance
