Small knowledge of SMD power inductors

Source: Company Dynamics Editor: PingShang Click: Release time: 2021-11-13 11:35:34

Overview: SMD inductors are also called: power inductors, high current inductors.

advantage:

1. Surface mount high power inductors.

2. Features of miniaturization, high energy storage and low resistance.

3. Mainly used in computer display boards, notebook computers, pulse memory programming, and DC-DC converters.

4. Reel packaging is available for automatic surface mounting.


Features:

Structure and coil technology realize low DC impedance and high allowable current;

Application of automatic surface loading with excellent weldability and environmental resistance;

Suitable for reflow soldering;

European RoHS certification;

Lead-free terminals;

The main parameters:

1. Error/precision

2. Inductance value: refers to the value of the road inductance tested at a frequency of 100Khz. So **different sense values are also slightly different

3. Self-resonant frequency: the frequency point where the inductance and the rich inductance form resonance. Therefore, in use, do not use the self-resonant frequency.

4. DC inductance: a large DCR value of winding inductance will cause heating

5. Saturation current: the current value when the inductance value drops by 30%
