Common Mode Chokes are widely used in various industrial and automotive applications, such as in the automotive field to achieve good EMI/RFI suppression, to reduce ESD stress, and for motor and power applications. One of these products is the PCMF2USB3B/CZ Common Mode Choke. This device is a high efficiency filter for reducing conducted EMI, especially for consumer digital applications. It is designed for high longitudinal mode, low DCR, and high current capacity. This device operates by using magnetic fields to "cut off" all other signals from the primary signal, thus eliminating line-to-line or line-to-ground noise.

The PCMF2USB3B/CZ Common Mode Choke is typically used in applications such as audio-video equipment, computer and office equipment, peripherals, SMPS, and home appliances. It offers many advantages over other types of filters, including a low DCR, better thermal dissipation, increased current capacity, high isolation, great cross talk reduction, and improved noise reduction. It can also be used together with capacitors for improved noise reduction and control. It has two terminals for the primary and secondary winding, and can be used for both differential and common mode noise suppression.

The working principle of the PCMF2USB3B/CZ Common Mode Choke is based on the electromagnetic principle of inductance. When the current moving in opposite directions flows through the two windings of the chokes, the changing magnetic flux generates an inductance in the chokes. This inductance is then used to cut off noise signals from reaching the device that it is connected to. The higher the inductance, the better the noise suppression.

The PCMF2USB3B/CZ Common Mode Choke is constructed with an internal ferrite core, which helps to suppress high frequency noises. It also has a shield to reduce EMI/RFI. The core has multi-turn and double sided winding to provide a high inductance for better noise suppression. The inner core is also made of high quality ferrite material, which helps to reduce DC resistance. The choke also has high isolation shielding, which helps to reduce cross talk and unwanted signals.

The PCMF2USB3B/CZ Common Mode Choke is a reliable filter for reducing conducted EMI in consumer digital applications. It has a low DCR, good thermal dissipation, and offers improved noise suppression. The choke is constructed with a high quality ferrite core and shielding, which helps to reduce EMI/RFI and cross talk. The choke is also longitudinally symmetrical, which helps to reduce DC resistance and increase current capacity. The PCMF2USB3B/CZ is an ideal choice for reducing noise in consumer digital applications, and can be used together with capacitors for a complete filtering solution.
