SRN6045-330M FAQ

What is a semi shielded inductor?

The performance of SMD semi-shielded inductor is the product between magnetic shielded and non-shielded products. The type in which the wound drum core is covered and molded with magnetic epoxy. The epoxy resin was blended with magnetic powder like soft magnetic metal.

 

What is shielded power inductor?

Magnetically shielded inductors minimize EMI while balancing small size with low DCR and high current ratings. Perfect as power chokes and for eliminating noise in power supplies in automotive, commercial, industrial, and high-reliability designs.

 

What are power inductors used for?

A power inductor is used in a step-up, step-down, or step-up/step-down circuit to convert a certain voltage to the required voltage. Among those different circuits, it is primarily used in a type of circuit called a “switching regulator.”

 

What is shielded and unshielded inductor?

Shielded inductors are manufactured to fully encapsulate the coil in a form of magnetic shielding. With unshielded inductors, the coil windings are typically exposed or otherwise magnetically not shielded. These are generally the worst offenders from an EMI perspective due to the unhindered propagation of EM fields.

 

How do you test an inductor?

Test an Inductor with a Multimeter in the Ohmmeter Setting for Resistance. The best test to check whether an inductor is good or not is by testing the inductor's resistance with your multimeter set to the ohmmeter setting. By taking the inductor's resistance, we can determine whether the inductor is good or bad.

 

What is a high current inductor?

Power inductors are used in electrical circuits where voltage conversions become necessary. High current inductors are specifically designed for high current, low voltage power supplies. Generally, these inductors have saturation current ratings above 100 Amps.

 

How does an inductor discharge?

If the inductor is taking the current from the source, the inductor is charging. If the inductor provides current to the load, the inductor is discharging. The current can be determined by using Kirchhoff's Current Law at any load.

 

Do inductors store energy by building up charge?

Inductors store energy by building up charge. An inductor always resists any change in the current through it. When it is connected in a circuit, an inductor always resists having current flow through it. An inductor always resists any change in the current through it.
