Fixed inductors, also known as fixed or nonvariable components, are devices that use a coil of conducting wire and a core material to store energy in a magnetic field.  The RL855-330K-RC is an example of this type of device, and its application field and working principle can be outlined as follows.

Application Field

The RL855-330K-RC is a series of shielded molded inductors designed primarily for use in radio frequency (RF) applications.  It is a low profile and easy-to-mount component that provides superior RF performance and is highly suitable for installation in portable, mobile cellular phone, and wireless communications systems.  It boasts excellent filtering capabilities and comes in an environmentally friendly lead-free package.

In addition, the RL855-330K-RC inductor can also be used in other applications such as switching power supplies, DC-DC converters, AC-DC converters, or other power circuits with high efficiency and low loss. The devices\' low height and non-magnetic cores make them ideal for use in space-constrained environments.  The space-saving molded body contributes to the inductor\'s reliability and helps to reduce audible noise in the operating environment.

Working Principle

The working principle of the RL855-330K-RC is similar to other types of fixed inductors.  It features a coil of conducting wire wrapped around a core material, typically made up of air, iron, or ferrite.  When an alternating current (AC) is passed through this coil, it sets up a varying magnetic field in the core, which in turn causes a varying voltage, or an induced voltage, across the coil. 

The RL855-330K-RC also uses a ferrite core material, which is characterized by its excellent thermal conductivity and low eddy-current losses.  The winding of the conductive coil is tightly wound around this ferrite core, which further increases the inductors efficiency and provides for a much lower resistance than other core materials.  This low resistance allows for greater current flow and higher power handling. 

The RL855-330K-RC has an RF inductance of 330nH and a parasitic capacitance of 60pF.  It also features a direct current resistance of 50 milliohms and a self-resonance frequency between 4 to 4.5GHz.  The component also provides excellent shielding against electromagnetic and radio frequency interference, further increasing its suitability for RF applications.

Conclusion

The RL855-330K-RC is a series of shielded molded inductors designed primarily for use in portable, mobile cellular phone, and wireless communications systems.  It boasts excellent efficiency and filtering capability with its low profile, environmental friendly, non-magnetic ferrite core, and its tight winding coil.  In addition, the component\'s shielding against electromagnetic and radio frequency interference make it a perfect choice for a variety of RF applications and circuits.
