SMT Power Inductors – DO1813HC Series
With rms current ratings up to 10 Amps, the DO1813HC
Series offers the high current, low inductance values
required for high power DC-DC applications.
These inductors are less than 0.2″ (5 mm) high. They
have very low resistance and a rugged self-leaded
construction.
Standard inductance values range from 0.18 to 48 µH
and custom values are available to meet specific
requirements.
Coilcraft Designer’s Kit C131 contains samples of all
inductance values. To order, please contact Coilcraft or
order on-line at http://order.coilcraft.com.
