Lead Type EMIFIL

BL0□/BLL/DSS1/VFC/PLT09/10 Series

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.

Ferrite Beads Inductor	BL01/02/03	・ Inductor type EMI suppression filters designed to operate from several MHz to several GHz. They are widely used as general- purpose noise suppression components to cope with relatively minor noise issues. ・ EMIFIL Inductor type filters behave as inductors with small inductance at low frequencies, while they produce a resistance- dominated impedance at high frequencies. When serially inserted into a noise transmission path, the resistance component absorbs and prevents the transmission of noise. ・ Effective in noise suppression A wide frequency range (several hundred MHz 30MHz of).
Ferrite Beads Inductor	BLL
Disc Type EMIFIL	DSS1	・ Capacitor type EMI suppression filters achieving a great noise suppression effect at frequencies between several MHz and several hundred MHz. Widely used as high-performance general- purpose EMI suppression filters. ・ The three-terminal structure decreases residual inductance and greatly improves the noise suppression effect at high frequencies greater than several dozen MHz.
EMIGUARD capacitor with varistor function	VFC	・ EMIGUARD filters combine a capacitor and a varistor, thereby providing both the surge suppression functionality of a varistor and EMI noise suppression functionality. ・ Meet the need to suppress both high-frequency noise and high voltage surge. Also effective against surges with extremely fast rise times that cannot be removed by conventional varistors.
Common Mode Choke Coil	PLT09H	・ Attenuate common mode noise that causes problems in balanced transmission lines. They effectively suppress common mode noise with frequencies from several MHz to hundreds of MHz, making them ideal for reducing noise in DC power supply lines, video and sound signal lines, and interface cables
Common Mode Choke Coil	PLT10HN	・ Highly reliable and supports large currents (up to 18 A)
