Ferrite beads and chips serve a variety of purposes, from providing additional electromagnetic insulation, dynamic load balancing, or EMI filtering to ensuring high signal integrity. The HR2220P601R-00, from Hotop Technology, is one such ferrite chip which can be applied in various telecommunications fields, and its working principle is analyzed in detail below.

The HR2220P601R-00 is a single-layer mononuclear ferrite chip inductor, with a balanced internal structure and excellent electrical performance. Its primary use is to reduce EMI noise, meaning it is perfect for suppressing EMI caused by high-frequent noise from line protection and system performance of communication devices. It can also be used as an impedance transformer, for example between transmission and reception signal lines. Consequently, it is perfect for use in electronic products such as phones, Bluetooth toys, laptops, and more.

The ferrite chip inductor HR2220P601R-00 features an inductance value of 1.6uH and a DC + resistance (DCR) value of 50 mΩ. It is formed from ferrite material and molded through plastic, scoring high in terms of thermal stability, moisture resistance, and ESD protection. Its high-frequency operation has advantages concerning attenuation performance, and it also has a uniform external inductance, very low residual magnetism, and low insertion loss.

The primary working principle of the ferrite chip inductor HR2220P601R-00 is inductance. Inductance is the physical property of a coil to resist changes in current. An inductor stores energy in a magnetic field created by placing coils of wire around a core (usually made of iron or ferrite material). The inductor can slow the rate of current change when connected to a voltage or, if it is connected to a circuit, it can contribute to high impedance.

In addition, the HR2220P601R-00 ferrite chip also has the function of EMI filter. In order to prevent radiated noise or cross-talk from leaking out of a device, the ferrite chip will be connected to the cables leading out of the device. The chip will attenuate the noise and filter it out to help reduce EMI interference from entering or exiting the device.

In summary, the ferrite chip inductor HR2220P601R-00 offers a variety of applications and unparalleled performance. It can be used as an EMI filter, an impedance transformer, or just to reduce EMI noise. Its working principle is inductance, in which it can create an electromagnetic field in order to resist changes in current in the circuit. Its remarkable features such as thermal stability, moisture resistance, and ESD protection effectively extend its application in phones, Bluetooth toys, laptops, and much more.
