Inductors, also known as coils, choke coils, or simply chokes, are passive electronic components mainly used in electrical circuits for filtering, coupling and tuning. Fixed inductors, also known as fixed coil, fixed chokes, or simply “fixed”, are one type of inductors with the most common and universal application. This article will discuss the application field and working principle of CDH53NP-2R2MC, which is a type of fixed inductor.

CDH53NP-2R2MC is a 10μH fixed inductor largely employed in DC/DC converters, power line filters, and other power supply circuits.

DC/DC converters use two different kinds of fixed inductors: one for an output-stage filter and the other for an input-stage filter, and CDH53NP-2R2MC is often used for either purpose. In particular, input-stage filters should be designed so that, even when the impedance of the power supply voltage is decreased, the inductor is able to keep the output voltage stable by blocking the input ripple. CDH53NP-2R2MC is capable of meeting this requirement since its resistance is lower than other types of fixed inductors.

Besides being used in DC/DC converters, CDH53NP-2R2MC can also be employed in power line filters. Since radio frequency (RF) interference effects have become increasingly serious in recent years, power line filters are needed to suppress RF interference and control the voltage ratio of DC current. CDH53NP-2R2MC is often used in such scenarios, because its working frequency range can be set in a large range, which is in compliance with most available requirements.

CDH53NP-2R2MC\'s working principle is based on Faraday\'s law, which states that an induced electromotive force (emf) is always generated when a conductor is placed in a variable magnetic field. When a current flows through the inductor, a magnetic field is generated around the conductor, and when the current changes, the magnetic field changes as well. According to Faraday\'s law, this changing magnetic field induces an emf in the conductor, and this emf opposes the current which generated it in the first place. This opposing force is what produces the inductance of the fixed inductor.

In summary, CDH53NP-2R2MC is a type of fixed inductor which is widely used in power supply circuits such as DC/DC converters and power line filters. Its working principle follows Faraday\'s law, in which an emf is induced when a conductor is placed in a changing magnetic field, and this induced emf is what produces the inductance of the fixed inductor.
