Fixed inductors are passive components which convert electric energy into magnetic energy and vice versa. Their primary purpose is to store energy or to change the frequency of alternating currents.

The 0819R-08K is a type of fixed inductor, sometimes referred to as an RFID inductor or a shielded ferrite core inductor. It is designed specifically for use in medium frequency radio frequency applications such as RFID technology. Its construction consists of a toroidal core wound with many find wires and encased in a shield.

The application field of the 0819R-08K is mainly medium frequency RFID applications. Its small size, low cost, and high efficiency make it ideal for use in RFID tags and readers, as well as any other application requiring low noise and low power consumption. The shielding feature helps to protect the inductor from electromagnetic interference.

The working principle of the 0819R-08K is relatively simple. When a current is passed through the circuit, the core tends to store energy in the form of a magnetic field. This in turn causes the output voltage to increase according to the number of turns in the winding. This increased voltage can then be used to power connected circuits such as an RFID reader. The core also acts as an impedance matching device, making sure that the power is distributed to the appropriate components.

In addition to this, the shielding provided by the inductor ensures that interference from external sources does not affect the operations of the RFID reader. This helps to reduce power consumption and give off less heat, thus making them ideal for use in portable applications. The shielding also helps to avoid signal fading due to interference.

Overall, the 0819R-08K fixed inductor is an ideal solution for use in medium frequency radio frequency applications such as RFID technology. Its small size, low cost, and high efficiency make it ideal for portable applications. It also comes with the added benefit of a shield for protection against interference, reducing signal fading and power consumption.
