Noise management technology focusing on EMC (Electro Magnetic Compatibility) is extremely important in order to effectively control EMI (Electro Magnetic Interference) and improve EMS (Electro Magnetic Susceptibility).
Murata meets the demands for noise countermeasure solutions for various applications, made possible through their vast experiences in the field coupled with the use of design support simulation software, enabling them to provide comprehensive support for their products.

Lineup
Chipped ferrite beads BL series
Inductor-type EMI suppression filters that are effective from several MHz to several GHz. As a general-purpose noise suppression component, they can be widely used for relatively mild noise suppression. Inductor-type EMIFIL behaves as a small inductance inductor at low frequencies, but generates impedance mainly consisting of resistance components at high frequencies. When inserted in series in the noise conduction path, this resistance component blocks and absorbs noise conductions.
Chip EMIFIL (3 terminal low ESL chip multilayer ceramic capacitor/LC composite type/Application-specific EMI filter) NF series
Inductor-type EMI suppression filters that are effective from several MHz to several GHz. As a general-purpose noise suppression component, they can be widely used for relatively mild noise suppression. Inductor-type EMIFIL behaves as a small inductance inductor at low frequencies, but generates impedance mainly consisting of resistance components at high frequencies.

Common mode choke coil/ common mode noise filter DL /PL /NFP series
Common Mode Choke Coils (CMCC) reduces the common mode noise that is problematic in differential transmission (ex. USB/HDMI/Mipi etc.), balanced transmission, power supply lines, and audio lines. They are ideal for suppressing common mode noise with frequencies ranging from several MHz to several hundred MHz with no adverse effect on the signals (upper cut-off frequency).

Murata offers a variety of lead type EMI suppression filters including: inductor type operating from several MHz to several GHz, capacitor type achieving a great noise suppression effect at frequencies between several MHz and several hundred MHz, and common mode choke coils ideal for noise suppression in DC power supply lines, video and sound signal lines, and balanced transmission interface cables. They can be widely used as high-performance general-purpose EMI suppression filters.
Block type EMIFIL BNX series
Noise suppression across a wide frequency band is possible in high current environments with a single product. They are ideal for noise suppression in DC power lines and can also be used for FA equipment and communication devices.
Audio line noise filter NFZ_S series/LQW_CA series
The NFZ series of noise filters for audio lines were developed as filters that combine noise suppression and audio quality.
These filters provide Class D amp noise suppression, high frequency isolation, and TDMA noise suppression while maintaining audio quality in speaker and earphone lines.
