B82114RC4

Ferrite Beads and Chips

B82114RC4 is a chip and ferrite bead integrated structure, belonging to the category of common mode inductors. The chip size and ferrite bead structure of this type of product are all the same. This type of product features very low DC resistance, small size, and high noise suppression ability. The use of B82114RC4 is particularly suitable for industrial and automotive electronic systems.

Application Field

B82114RC4 has a wide variety of application fields due to its strong anti-interference performance. In the smart home and home appliance field, it can be used as a signal line filter, suppressing the interference produced by the main power supply; in industrial control field, it can be used to prevent PLC digital input/output from being interfered by external electromagnetic signal, ensuring the accuracy; and in the new energy automotive field, it can be used to filter the power supply of car control system and reduce the interference produced by the unstable power supply. In a word, B82114RC4 can be used in any field where the noise interference is a problem for signal accuracy.

Working Principle

B82114RC4’s working principle is based on the multiple shielding structure, using the small winding radius of chip structure to form two small air gaps in the inductance. These two air gaps can effectively reduce the inductance value and achieve the electrical performance of high frequency. In addition, the ferrite bead integrated structure has a very strong shielding effect. When the external interference signal enters B82114RC4, it will be blocked effectively, achieving signal insulation and noise suppression. As a whole, this structure is effective in preventing leakage or emission into external condominiums on common mode, so as to reduce the signal interference and improve the signal accuracy.
