Common Mode Chokes - DLW5BTH142TQ2K application field and working principleCommon Mode Chokes (CMCs) are components that filter and suppress noise or signal interference within a current carrying path. They are usually small in size and primarily operate in switching power converters, high-frequency communications equipment, noise reduction systems, and in industrial and commercial equipment.DLW5BTH142TQ2K is a type of Common Mode Choke with various specifications such as frequency range, rated current, insertion loss, equivalent I/O capacitance, and switching frequency. It has a high self-inductance and can block common mode noise in the frequency range up to 600 MHz. The DLW5BTH142TQ2K Common Mode Choke is mainly used in high-frequency switching power converters offering excellent attenuation of common mode noise at various input and output range of frequencies. The choke can efficiently filter out unwanted noise and prevent it from being conducted to the primary circuit or even the secondary circuit.This choke can also reduce the risk of equipment breakdown from electromagnetic interference or switching pulses generated by other equipment. The robust design makes it suitable for applications where excessive noise is likely to occur, such as those in industrial electronics, power supply units, and battery charge systems.The DLW5BTH142TQ2K Common Mode Choke works by creating a small impedance in the current flow circuit, allowing the unwanted currents to be blocked, mainly due to the self-inductance of the internal coil. The internal coil is typically made of a ferrite core which is embedded within a cylindrical housing. This toroidal ferrite core is wound with multiple coils, forming a series of inductive loops, which impedes the flow of current both in steady state and transient conditions. It also offers excellent filtering characteristics for signals at various frequencies. The high efficiency of the choke allows it to reduce noise interference from other electronic components such as motors and power switches, which would otherwise disrupt the normal operation of the device. Since it blocks common mode currents, it also helps reduce EMI radiation and increases system immunity to EMI. In addition, the DLW5BTH142TQ2K Common Mode Choke can also be used in contactor circuits to reduce the switching delay of power switching devices. This allows them to operate faster than normal and reduces the risk of false triggering due to transient noise.The choke can also be used in applications which require filtering of a voltage or current signal. In these cases, the choke is placed in between the signal source and destination, allowing only the intended signal to pass through. This also reduces the chances of interference from other electrical devices. All in all, the DLW5BTH142TQ2K Common Mode Choke can be effectively used in a wide variety of applications, where low noise levels and reliable operation are required. It offers a high degree of EMI filtering, and is able to filter out high and low frequency signals simultaneously. It is also a cost-effective solution that provides excellent attenuation of common mode noise for applications up to 600 MHz.
