LQM21P Series Multilayer Inductors

As mobile devices become increasingly multifunctional they are being designed to become smaller and thinner, as well as, incorporating a greater number of DC/DC Converters to drive dissimilar voltages of camera, radio, and television functions. In addition, higher packaging densities are expected in power supply circuits of mobile devices along with higher switching frequencies above 1 MHz. Thus, in designing and selecting an ideal inductor for use with a DC/DC converter in mobile devices, an engineer must consider the effects produced by the implementation of higher switching frequencies and higher packaging density in power supply circuits.

To meet this growing inductor requirement for higher frequency switching DC/DC converter applications within mobile devices, Murata Electronics has released the LQM21P series. The LQM21P series are multilayer inductors packaged in a compact 0805 package with a maximum height of 0.55 mm. Utilizing Murata Electronics original ferrite material technology and innovative structural design has allowed for the following features to be incorporated into the LQM21P series inductors:
