This family of surface mount Midi Spring
designed for higher current applications (up to 3.5 Amps)
than our smaller series. It also provides higher Q factors
at lower frequencies.
Like all Coilcraft “spring” inductors, these parts provide
the advantages of an air core inductor in a package
optimized for auto placement. The top of the coil is
capped with acrylic, forming a flat surface and assuring
mechanical stability. The leads are solder coated for
reliable soldering.
Coilcraft Designer’s Kit C118 contains samples of all
5% inductance tolerance parts. Kits with 2% tolerance
are also available. To order, contact Coilcraft or visit
