Fixed inductors are electronic components often used in applications such as power supplies, RF applications, switching regulators, and other similar situations. The CDRH3D28/LDNP-470NC fixed inductor falls into this category and has specific applications and working principles that are important to understand.

The CDRH3D28/LDNP-470NC is a toroidal ferrite core power inductor designed for use in DC/DC converters, switching regulators, AC/DC adapters, motor control, power factor correction circuits, and pulse transformer circuits. The inductor has high inductance stability due to its toroidal ferrite core and is rated with a ripple current up to 7.5A. Power handling on the inductor is up to 1.5W at 80°C with main inductance values range between 36µH to 10mH.

The CDRH3D28/LDNP-470NC has a compact design and a low profile. It is manufactured as an integral part of a shielded cover, which in turn makes it suitable for use in high density applications. The shield also provides a degree of protection from EMI/RFI noise, reducing system interference. The inductor also features a wide operating temperature range, with a rated temperature up to 85°C.

The basic electrical working principle for the CDRH3D28/LDNP-470NC is the same for most inductors. When an electrical current runs through an inductor, a magnetic field is generated around the current-carrying winding. This magnetic field induces a voltage into the winding, which opposes the initial current. This process is known as electromagnetic induction and is responsible for the inductor’s ability to store energy. The induced voltage works to reduce the current, and the energy stored in the inductor is proportional to the square of the current running through it.

The CDRH3D28/LDNP-470NC fixed inductor is built using a high-end toroidal ferrite core, allowing for a high inductance stability. This type of inductor provides power handling up to 1.5W at 80°C and a wide operating temperature range up to 85°C. Its compact shielded design provides a degree of protection from EMI/RFI noise, while also making it suitable for high-density applications. The inductor’s working principle is based on electromagnetic induction, which is the process allowing it to store energy proportional to the current running through it.
