Common Mode Chokes

Common Mode Chokes, also known as common mode inductors, are used to reduce electromagnetic interference in signals or power supply lines. Common mode chokes provide differential or common mode impedance to high frequency line noise. The TCK-151 is a common mode choke specifically designed to provide attenuation of common mode noise and high-frequency interference in automotive power and signal lines.

Working Principle

The TCK-151 works by creating an electrical current that passes through two coils of wire which are wound around an iron core. This electrical current creates a magnetic field which surrounds the wires and core. The magnetic field induces an inductance in the wire, which resists the flow of current to the coils. The degree of inductance depends on the number of turns of wire, the size of the core, and the amount of magnetic material in the core. The TCK-151 is designed with a special high-frequency alternating current coil to maximize its attenuation characteristics.

Attenuation Characteristics

The TCK-151 is designed to offer exceptional common mode noise attenuation characteristics. It is rated for operation up to 20kHZ and can attenuate common mode noise up to 40dB or more in some applications. It is especially useful in automotive applications, where high-frequency interference is a common problem and can be difficult to manage.

Applications

The TCK-151 is used in a variety of automotive applications, including power converters, signal lines, and audio systems. It is often used to reduce common mode noise in power lines, signal lines, and audio systems by providing an effective shield against the high-frequency interference. Common applications include car audio speakers, power converters, and automotive control systems.

Advantages

The TCK-151 offers a wide range of advantages over other common mode chokes. It has exceptional attenuation characteristics and is capable of reducing common mode noise up to 40dB or more in some applications. It is also designed for easy installation, as it requires no welding or soldering. Additionally, the TCK-151 is designed to be lightweight and compact, making it easier to install in tight spaces.

Conclusion

The TCK-151 is an effective common mode choke designed to provide excellent attenuation characteristics in automotive applications. It is designed for easy installation and provides NEMA-grade protection. The TCK-151 is a cost-effective solution to the problem of interference from high-frequency noise in automotive power and signal lines.
