Common Mode Chokes, represented by TCK-077, are electronic components that are used to block high-frequency interference in transmission circuits. They are used in many industries, including automobile, home appliance, medical device, consumer electronic, aerospace, and communication.TCK-077 Common Mode Chokes are designed to have superior electromagnetic shielding capability, low current leakage, and good temperature stability. They are able to attenuate common mode interference, which is when an external electromagnetic interference is conducted in both lines of a single-phase power supply or data line. TCK-077 is composed of two magnetic inductors connected in parallel. Each of them has a core of ferrite material, windings, and characteristics of a common mode filter. The inductance value of each magnetic inductor in the TCK-077 is designed such that it can effectively suppress noise of different frequencies.The working principle of TCK-077 is to create a differential inductance between the two lines of the power line or data line. When high frequency interference signals are present, it prompts the differential mode inductance to reject the noise by generating an inductive voltage in the lines. The differential mode inductance of the TCK-077 is designed to increase with the rise of frequency, allowing it to effectively attenuate high frequency interference signals. Meanwhile, the two inductors of the TCK-077 can generate common mode rejections as well by creating an inductive voltage along the two paths of the power line or data line. The common mode inductance is designed to be relatively constant, providing a consistent level of filtering and shielding against common mode noise signals.In addition to electromagnetic shielding capability and low current leakage, the TCK-077 also features great temperature stability. It is designed to operate within a wide temperature range and to be immune to the effects of changing temperatures. It can also withstand mechanical vibration and strong impacts, ensuring its long-term reliability. Moreover, its miniscule form factor and easy to install Binder Clip design make it convenient to use for a variety of applications.The TCK-077 Common Mode Chokes have a broad range of applications, and are ideal for use in a variety of power and data lines that require noise suppression and electromagnetic shielding. They are widely used in a variety of electrical and electronic equipment, including power inverters, motor drives, PLCs, medical equipment, automotive electronics, and consumer electronics. The TCK-077 can also be used in power and data lines with single-phase power sources or data transmission, such as variable frequency drives, switching power supplies, and industrial communications. The Common Mode Chokes help reduce the amount of EMI that is generated by these systems and prevent EMI energy from being conducted into other parts of the system or other equipment.In conclusion, TCK-077 Common Mode Chokes are an ideal choice for protecting against power line or data line noise. Their superior filtering and shielding, low current leakage, temperature stability, low form factor, and easy installation make them ideal for a wide variety of applications. As such, they are a reliable and effective way to keep noisy interference away from sensitive systems.
