Fixed Inductors

Fixed Inductors (or chokes) are passive components used to ensure noise immunity or filter ripple current in many different types of electronic circuits. The VLF504015MT-6R8M-CA is a type of fixed inductor and the section below looks at the different applications in which it is used as well as the working principle behind it.

Applications

The VLF504015MT-6R8M-CA is a medium power inductor which is an ideal choice for use in power supply designs, especially those with relatively low f-sw frequencies and moderate efficiency requirements. As such, it is commonly used in switch mode power supplies (SMPS), DC to DC converters and battery chargers. The VLF504015MT-6R8M-CA is also commonly used in high-reliability automotive, medical and industrial applications due to its combination of high operating temperatures and high surge current capability.

Working Principle

An inductor works by storing energy in the form of a magnetic field, resulting from the current flowing through its windings, when a voltage is applied across it. When an alternating current (AC) supply is used, the magnetic field will collapse and impart an opposing voltage across the inductor\'s terminals, thus producing an \'inductance\' effect. The amount of current an inductor can handle depends on the number of turns in its windings, the size of the core material and its shape. This makes the characteristics of the VLF504015MT-6R8M-CA an ideal choice for many power supply designs, as it has a high current handling capability and a small form factor.

In addition, the VLF504015MT-6R8M-CA inductor also has the unique ability to dissipate the EMI frequency noise. This is due to its low residual inductance and Self-Resonant Frequency (SRF), which makes it ideal for use in higher power switch mode power supplies and DC to DC converters. Therefore, the VLF504015MT-6R8M-CA offers excellent noise suppression and power supply filtering capability.

Conclusion

The VLF504015MT-6R8M-CA is a type of fixed inductor, and is a popular choice in many power supply designs due to its compact size and high current handling capabilities. It is especially suited for high-reliability automotive, medical and industrial applications due to its high operating temperatures and high surge current capability. In addition, the VLF504015MT-6R8M-CA has a unique noise suppression ability, due to its low residual inductance and SRF which makes it ideal for use in power supply designs.
