Panasonic EXC24CN, EXC24CB-CP User Manual

2 mode Noise Filters

Typ e:

EXC24CB/CP

EXC24CN

2 mode Noise Filters

■ Features

● Burst/radiation noise fi ltering for audio circuits

● The optimally magnetic-coupled ferrite beads allow for

the fi ltering of both common and normal mode noises

● The strong multi-layer structure provides high resistance
to refl ow soldering heat and a high mounting reliability

● Magnetic shield type

● High Impedance : 220 to 1 k액（EXC24CB type)

● Low Resistance Value : 0.4 액 max. (EXC24CP type)

● High Impedance : 600 액,

Low Resistance Value : 0.9 액 max. (EXC24CN type)
