Features
• Miniature SMT wire-wound open
magnetic path construction inductors
with low DCR, high current capacity
and High Impedance Characteristics.
• Excellent solder heat resistance for
flow and reflow soldering methods.
• Excellent for use as choke coils
in DC/DC converter and DC power
supply circuits.
