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 in mobile phones, digital still cameras, radios, and televisions. 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 new lower profile mobile devices, Murata Electronics has released the LQH2MC_52 series inductors. The LQH2MC_52 series are wire wound inductors packaged in a compact 0806 size with a max height of 0.70mm, making them ideal for low profile applications. Utilizing Murata Electronics original wire wound technology and innovative structural design has allowed for the following features to be incorporated into the LQH2MC_52 series low profile inductors:

Features:

• Small size in 2.0 x 1.6 x 0.70mm package (0806 size )
• Low Profile with low profile max height of 0.70mm
• Stable inductance across the frequency range
• High Self Resonance Frequency (SRF)
• Low DC Resistance
• Inductance range 1.0uH to 10uH
• Large rated current of 595mA (1.0uH)
• Ideal for high frequency switching circuits above 1 MHz
• Reflow solderable
• RoHS Compliant

Applications:

• DC – DC Converters
• White LED Drivers
