Midcom, Inc.
NASCENTechnology division has developed a family of inductors to demonstrate what can be done
using Low Temperature Co-fired Ceramic (LTCC) technology. Although primarily designed for portable battery pow-
ered applications where low profile and rugged construction are critical, these inductors will find use wherever a low
cost solution is desired. Since the windings are completely enclosed by ferrite, superior EMI characteristics are
noted. Sized in between typical “chip” inductors and drum cores, the new Midcom inductor series has DC bias
characteristics closer to drum cores, while being able to withstand DC bias overloads without totally saturating. In
addition, the construction materials used can withstand high temperatures without degradation.
