Common mode chokes, also known as differential mode chokes or EMI filters, are special filters that are used to reduce electrical noise from external sources, such as a power supply, or in electronic circuits. Common mode chokes use inductors to provide a low-impedance path for unwanted noise currents and to block high-frequency noise. They are most commonly used to reduce the amount of EMI (electromagnetic interference) that can affect sensitive electronic devices such as computer networks and medical devices.

The NFP0RSN112HL2D is a common mode choke developed by Murata Electronics, which is a global leader in electronic components and systems. The part consists of two ferrite-core coils wound in opposite directions and connected in series. This design creates a low impedance path for unwanted currents, such as common mode noise, and blocks high-frequency noise. The NFP0RSN112HL2D is designed with two separate inductors, allowing each one to block independently. This feature provides better overall protection for sensitive equipment against EMI.

The application field of NFP0RSN112HL2D includes many applications in various fields. For example, it can be used in industrial, home electronic and automotive equipment for protecting a variety of different circuits from high-frequency noise. The NFP0RSN112HL2D is also used in computer networks, medical devices, and other sensitive electronic equipment to reduce the interference from interference sources. It is also used to provide reduction in crosstalk and noise in communication lines.

The working principle of the NFP0RSN112HL2D is relatively simple but effective. The two inductors work together to provide the low impedance path needed to reduce the noise currents. The inductors used in the NFP0RSN112HL2D have two separate terminals; one connected directly to the source of the interference and the other connected to ground. When interference is present on the source terminal, the NFP0RSN112HL2D will act as a filter and reduce the noise current, while allowing the useful signals to pass through. This filtering effect is achieved by the inductors creating an electromagnetic field that blocks the interference, and the useful signals pass through unaffected.

In addition to providing protection against noise currents, the NFP0RSN112HL2D filter also provides high common mode impedance. This is achieved by effectively cancelling out unwanted noise currents, while allowing the useful signal to reach its destination. The high common mode impedance also helps to reduce the crosstalk that can occur in communication systems, allowing for clearer communication.

Overall, the NFP0RSN112HL2D is a great choice for reducing EMI noise and providing effective protection for sensitive equipment. Its two-part design makes it suitable for a number of applications, while providing excellent performance. Additionally, its high common mode impedance offers additional benefits, such as reducing crosstalk in communication systems. The NFP0RSN112HL2D is an ideal choice for any user who needs to reduce noise from interference sources.
