Maxi Spring™ Air Core Inductors
Designed for higher current applications (up to 3.5 Amps),
these surface mount Maxi Spring™ air wound coils
provide inductance values up to 538 nH and exceptionally
high Q factors, even at low frequencies.
They’re packaged in a rigid, flat top package that makes
them compatible with pick and place equipment. The
leads are solder coated for reliable soldering. And because
the coil is locked in position, precise terminal spacing is
guaranteed.
Coilcraft Designer’s Kit C119 contains samples of all 5%
inductance tolerance parts. Kits with 2% tolerance are also
available. To order, contact Coilcraft or purchase on-line at
http://order.coilcraft.com.
