SNC Series
Differential Mode Choke Coils for Signal Line and DC Power Line
SMD
FEATURES
• SMD type power choke coils in which low loss amorphous alloy
are used.
• SNC series are suitable for choke coils for DC to DC converters
required high efficiency and used in battery-driven equipment
such as notebook PC.
• Very low leakage magnetic flux achieved by its gapless struc-
ture.
• High power type SNC12560 type(H6mm) and low profile type
SNC12550(H5mm) are available.
• Suitability for power lines with direct current of 5 to 10A.
APPLICATIONS
Smoothing choke coils for DC to DC converters
Set applications: Notebook PCs, desk-top PCs, word processors,
switches
