    What are the main characteristics of iron powder core inductors?


The main characteristics of iron powder core inductors are as follows:

1. Iron powder core density distribution has better temperature stability.

2. It is less expensive than other alternative magnetic cores.

3, the shape of the chip inductor can supply flexibility and variability when necessary, but the cost is higher.

4. The use of high magnetic loops for SMD power inductors is usually found in power supply DC/DC converter circuits.

5. Another performance trade-off can be seen in the inductor current, inductor voltage (pin 14 to pin 16) and output voltage ripple typical waveforms.

6. Using a smaller inductor, the fdv0620-0.47μh inductor produces a higher peak current and the output voltage ripple is less than 18mV peak-to-peak.

7. The peak value of the ripple generated by the chip inductor is just over 12mv. The peak current charges the output capacitor and supplies the load current.

8. Large currents will flow in and out of the capacitor, which will produce higher output voltage ripple.

9. SMD inductors are mostly used in power supply filtering circuits. Inductors are energy storage components that focus on suppressing conductive interference.

10. SMD Power Inductors Inductive components and EMI filter components are used extensively in the device's pad circuit.

11. Inductive elements and EMI filter elements are widely used in pad circuits of electronic equipment

A large number of inductive elements and EMI filter elements are used in pad circuits of electronic devices.

12. In the circuit, the inductor must have a high Q, a narrow inductance deviation, a stable temperature coefficient, in order to achieve the narrow band, low frequency temperature drift requirements of the resonant circuit. High-Q circuits have sharp resonant peaks.
