The 3631 series of SMD shielded
Power Inductors are designed to
handle high current and have been
designed for use in SMD power
circuits. With the superior ferrite core
material and its low profile construction
we can ensure excellent inductance
characteristics coupled with proven
Tyco Sigma quality.
