FEATURES
• A chip-type common mode filter for high current applications.
Common mode impedance surpasses 600 to 1000Ω at 100MHz.
Noise is greatly suppressed.
• Capable of handling the highest current (up to 6A) of any chip-
type common mode filter.
• This series of choke coils handles a range of current settings
from 1 to 6A.
• Height and size have been considered, resulting in a compact
and light-weight choke coil. Applicable for the miniaturization
required to reduce the size and weight of portable equipment.
APPLICATIONS
Used for power line noise suppression for any electronic devices.
Used to counter adapter/battery line noise for relatively large elec-
tronic devices such as notebook PCs, stand-alone word proces-
sors, etc.
