CIM05J221NC

Ferrite beads and chips are used in electronic circuits for purposes of signal filtering and suppression of electromagnetic interference (EMI). The CIM05J221NC is one such ferrite bead, and is used in a variety of applications. In this article, we shall discuss the application field and working principle of the CIM05J221NC.

The CIM05J221NC belongs to the class of common mode chokes, which are used for power line interference suppression and noise filtering. Common mode chokes are made up of two identical winding coils arranged in a symmetrical configuration, with a ferrite core. They are fed with two signals of equal amplitude but with 180-degree phase shift relative to each other. The common mode choke distinguishes between the common mode and differential mode signals, allowing the differential mode signals to pass while blocking the common mode signals.

The CIM05J221NC is a SMD (surface mount device) ferrite bead which has a rated impedance of 2.2 Ohm and can handle peak currents of up to 6A. It has a working temperature range of -40°C to +85°C and can be used in a variety of electronic circuits. It is commonly used to suppress EMI (electromagnetic interference) emitted from digital and analog circuits. Examples of applications include automotive electronics, computers and peripherals, as well as in consumer electronic products. The CIM05J221NC has good ESD (electrostatic discharge) performance and will not excessively distort the signal waveforms in the frequency range of 100kHz to 10MHz.

The main principle behind the CIM05J221NC is the inductive and capacitive reactance. Inductive reactance is the opposition by a coil to the flow of current caused by a changing magnetic field. Capacitive reactance is the opposition by a capacitor to the flow of AC current caused by the reactance of the capacitor against a changing voltage. The ferrite core acts as an inductor while the capacitor prevents destructive resonance from occurring. As the ampere-turns of the coil is constant, the impedance offered by the CIM05J221NC remains constant over a wide range of frequencies.

In conclusion, the CIM05J221NC is a common mode choke with a rated impedance of 2.2 Ohm and can handle peak currents of up to 6A. It is commonly used to suppress EMI (electromagnetic interference) emitted from digital and analog circuits, and can be used in a variety of electronic circuits. The main principle behind the CIM05J221NC is the inductive and capacitive reactance, with the ferrite core acting as an inductor while the capacitor prevents destructive resonance from occurring.
