Power Line Filter Modules 05DBAW5 Application Field and Working Principle

Power Line Filter Modules (PLFMs), such as the 05DBAW5 series manufactured by TDK Electronics, are an important part of the electronic system. They are utilized to protect against the fluctuations on the AC power line caused by external environment or equipment.PLFMs such as the 05DBAW5 are designed for general purpose, bidirectional applications such as AC-DC telecom power supplies, medical equipment, industrial appliance, lighting applications, and so on. They are mainly used in installations where both line to earth and line to line operation can be encountered. It can provide transformer type line to line filtering as well as a shunt type line to ground filter in the same module.The key features of the 05DBAW5 are its wide common mode EMI suppression capability (12.5A rated common mode current) and high differential mode EMC suppression capacity (current up to 1.8A). The 05DBAW5 is a three-stage filter module with different performance characteristics. This includes high common mode impedance, excellent differential mode impedance, and excellent differential mode noise suppression.

Working Principle

The 05DBAW5 functions primarily as an AC-DC blocking filter, providing protection against high frequency AC power line disturbances. It consists of various components connected in series, including a choke coil, an AC-DC blocking capacitor, a bypass capacitor, and a resistor.The choke coil, also known as a power line choke, attenuates the common mode current on the AC power line. This effectively limits the transmission of high frequency components, acting as a very low-pass filter that prevents high frequency noise signals from entering the power line.The AC-DC blocking capacitor then filters out any remaining high frequency components. It is usually in the range of several microfarads, and works on the principle that direct current (DC) cannot pass through a capacitor. The bypass capacitor is placed in parallel with the AC-DC blocking capacitor, and it provides noise attenuation in the line. Finally, the resistor provides high-frequency noise suppression in the opposite direction, permitting a higher amount of common mode current to flow.

Performances

The 05DBAW5 offers superior protection against high frequency disturbances. It has a rated common mode current of 12.5A while providing a high differential mode EMC suppression capacity of 1.8A. It also has a high differential mode impedance and excellent common mode impedance. Noise suppression is provided with a full-scale RFI shielding effect of up to 40db.In addition, the 05DBAW5 offers excellent UV and ESD protection, which means it can withstand extreme electrical and environmental stresses. It also has a rated temperature range of -40-105℃, which allows it to be used in a variety of extreme environments.

Conclusion

The 05DBAW5 Power Line Filter Module from TDK Electronics is a reliable and cost effective solution for protecting against AC power line disturbances. It offers superior protection against high frequency disturbances, and provides high differential mode impedance, excellent common mode impedance, and reliable common mode current limiting. Its UV and ESD protection capabilities make it suitable for use in extreme environments. With its wide range of features, the 05DBAW5 is an excellent choice for any application requiring appropriate AC power line filtration.
