Fixed inductors are electrical components made with a tube-like structure. They are used for inductive electrical power storage and release for a variety of applications. The 1330R-16K, a fixed inductor manufactured by Murata, is used in sensing, motor control, and power applications. This article provides an overview of 1330R-16K’s application field and working principle.

Application Field

Murata\'s 1330R-16K is an ideal inductor for a wide range of applications. Its low DCR (1.8mΩ) and coil metalization make it an ideal choice for low frequency switching power supplies, as it can handle current up to 3.2A.

In motor control applications, the 1330R-16K’s low DCR helps reduce heat generated by the inductor. The low DCR also helps minimize heat in other applications, such as for USB power source lines and DC/DC converters.

The 1330R-16K’s large inductance is also beneficial for its application in such appliances as refrigerators in order to maintain a constant power output from the appliance\'s power supply. It is also well suited to filter EMI (electromagnetic interference).

Working Principle

The 1330R-16K fixed inductor works by maintaining electrical power within its core, which is made of ferrite material. When a current passes through the inductor, magnetic fields build up around it, producing an opposing force to the current which signals the inductor to store electrical energy. This increases its inductance.

When the current is cut off, the magnetic fields around the inductor slowly dissipate, causing the inductor to release its stored electrical energy in the form of an induced voltage. This process is known as back-EMF (electromagnetic force).

The 1330R-16K fixed inductor also offers high permeability and good saturation characteristics. This enables the inductor to handle higher-frequency applications, such as wide bandgap ICs (integrated circuits).

The 1330R-16K fixed inductor is also capable of handling wide temperature ranges, making it suitable for temperature-sensitive applications. This makes it an ideal choice for automotive applications requiring low temperature tolerance.

Conclusion

The 1330R-16K fixed inductor is an ideal choice for an array of applications. Its low DCR and coil metalization make it a great fit for low-frequency switching power supplies and motor control applications. Its large inductance and good saturation characteristics make it well-suited to filter EMI and handle higher-frequency applications. The 1330R-16K also offers a wide temperature range which makes it suitable for automotive applications. For these reasons, the 1330R-16K is an excellent choice for fixed inductor applications.
