EXC-18CS350U Filters

Common Mode Chokes are special electrical components used to isolate signals and reduce electromagnetic interference (EMI) or crosstalk between two devices or lines. The EXC-18CS350U is a type of common mode choke used when high frequency signals pass between two circuits. It can reduce common mode noise while allowing the same signal to safely pass in differential mode, making it useful for signal integrity applications.

The EXC-18CS350U\'s specs include a DC resistance of 0.8 Ω, and an inductance of 370 nH. The operating temperature range is -40 to +105°C, and its operating frequency range is 0 ~ 9GHz. It has a compact size of 12.5x8.5mm, making it suitable for use in small areas.

The Working Principle of the EXC-18CS350U follows Maxwell’s equations, which states that an electric current generates a magnetic field which in turn generates an electric field. The EXC-18CS350U consists of an inductor and capacitor connected in series. This arrangement forces the current flowing through the circuit to transfer in a single direction, thus reducing any interference caused by common mode noise.

The EXC-18CS350U is able to reduce common mode noise in applications such as in telecom networks, CATV systems, and WiFi systems. It can be used in other applications such as power supplies, MP3 players, sound and video recorders, broadcast equipment, and in industrial control systems. Due to its ability to reduce EMI and provide signal integrity, it is also used in high-speed data transmission lines and digital signal processing systems.

The EXC-18CS350U can be used for signal isolation and conditioning in a variety of devices that require reduced EMI or crosstalk. It can ensure that a signal sent between two circuits or components remains intact due to its ability to provide good signal integrity and reduce common mode noise.
