ELF-19N032A

Common Mode Chokes

Common Mode Chokes, also known as common mode inductors or filters, are special types of electromagnetic components used for reducing and filtering common-mode noise in electrical circuits. The ELF-19N032A is an example of this type of choke, and it is designed for high-impedance environments where noise needs to be filtered and reduced while still maintaining a high level of efficiency. The ELF-19N032A is also a much more cost-effective option for applications on a budget.

Application Field

The ELF-19N032A is a high current filter primarily intended for applications in motor and industrial control systems, as well as in telecommunications applications where high impedance is desired. It is also well-suited for general power line applications, and it has been tested in temperatures ranging from -50°C to +150°C.

In motor control applications, the ELF-19N032A’s high current handling capability and high efficiency make it an ideal choice for noise reduction. It can also be used in electronic ballast circuits, LED lighting applications, and power factor correction equipment to reduce the level of common-mode noise that can interfere with the operation of these systems.

In telecommunications, the ELF-19N032A can be used to reduce common-mode noise that can interfere with radio signals and data transmission. It is also well-suited for power line EMI/RFI noise filtering in systems where a high level of efficiency is required.

Working Principle

The ELF-19N032A is an electromagnetic component that functions by using a combination of inductance and capacitance to filter out undesired noise. The 4-terminal design allows the device to provide increased power handling capabilities and increased current-handling capabilities compared to 3-terminal designs, making it better suited for power line noise reduction applications.

The ELF-19N032A also includes a ground shield which helps reduce the amount of EMI/RFI noise that is allowed to pass through the device. This shield also helps reduce the amount of power that is lost due to leakage current, which can make the device more efficient compared to other choke designs.

Overall, the ELF-19N032A provides a high level of efficiency and power handling capability, making it a great choice for noise reduction and power line filtering applications. It is also much more cost-effective compared to other choke designs, making it an attractive option for applications on a budget.
