CDRH10D48/ANP-470MC Application Field and Working Principle

Fixed inductors are electrical components with inductance rated at a specific value. The CDRH10D48/ANP-470MC is a specific type of such a fixed inductor, which is mainly used in power electronic circuits, switch-mode power supplies, and very-low-noise signal conditioning or amplification circuits. This device is especially noteworthy due to its very low profile and small size, making it ideal for applications which require a discrete inductor with few physical components.

Working Principle

The CDRH10D48/ANP-470MC\'s working principle involves applying a time-varying electromagnetic force (EMF) across a wound coil of metal. This force creates an unbalanced radial electromagnetic field, which can induce voltage across the inductor, referred to as self-inductance. The self-induced voltage itself acts to reduce the EMF and the presence of the inductor therefore causes the current to ramp up and lag the voltage. This decrease in the EMF results in the current flow being delayed by some factor, depending on the inductance.

Moreover, this inductor is able to self-regulate the current and voltage in a circuit, providing vital frequency controlling properties. This means that the inductor will be able to resist changes in application conditions and the output will remain relatively constant. This same property also allows the CDRH10D48/ANP-470MC to become an ideal filter for unwanted, high-frequency noise, resulting in much cleaner waveforms.

Application Field

The CDRH10D48/ANP-470MC has a wide range of applications due to its low profile and small size; applications that do not have room for larger inductors are perfect for this device. This inductor is often used in power electronic circuits, such as switch-mode power supplies, pulse-width modulation, and the like, where its self-regulating current and voltage properties are a necessity. Furthermore, this component is beneficial in very-low-noise circuits, specifically signal conditioning as the EMI filter it provides helps reduce the presence of unwanted noise.

These advantages are not exclusive to large-scale electronic applications; the CDRH10D48/ANP-470MC is often found in mobile devices, such as cellphones, music players, and other portable devices, as its size and form factor make it perfectly compatible.
