Common Mode Chokes (CMCs) are passive electrical components used to attenuate or filter common mode noise from either AC or DC signals. CMCs are commonly used in areas such as industrial, commercial, automotive, and telecom applications. PH9455.105NL is a type of CMC, which is specially designed for applications where a high-frequency, wide-bandwidth signal is needed, such as data communications on high-speed networks.

The PH9455.105NL CMC is designed to operate from DC up to 65MHz and is rated at 25A with an impedance of 300 Ohms. It has a wide operating temperature range of -55°C to +125°C and is available in a 14-lead surface-mount metal-shielded package. This type of CMC is ideal for applications requiring filter or noise attenuation, such as in motor drives, inverters, and power supplies.

The PH9455.105NL works by absorbing any common mode noise on the signal line and preventing it from propagating further. This is done by creating two absorbing coils connected in series in a loop around the signal line. The coils create an inductance that causes a phase shift which causes current on the signal line to be out of phase with the surrounding noise. This out-of-phase current is then absorbed in the coil, effectively filtering the common mode noise from the signal.

To further enhance the noise-filtering capabilities of the PH9455.105NL, a metal-shielded package is used. This package helps to reduce the amount of noise interferences that may exist in the area surrounding the CMC. Additionally, the design of the coil is optimized to properly dissipate and absorb any interferences. This combination allows the CMC to provide a high level of performance while also being cost-effective.
