RF InductorProposal of the base exclusive possession area reduction by small size, the high-performance LQP03_02 series

Comparison of Number of Inductors used in Conventional Mobile Phones vs. 3G/LTE Smart Phones

In recent years, along with the increase in the number of transmission bands used for mobile phones (smart phones), the number of small size inductors used for RF matching and RF chokes is increasing. The needs for small size components are also increasing, along with the overlapping of the demands for small size sets and thinner sizes.

Proposal for Small Sizes by Downsizing of Inductors

- Size Comparison of Individual Components -

Murata proposes the 0603 mm (0201 inch) size LQP03_02 series for future designs of 3G/LTE smart phones.

Size Comparison of Individual Components

0.18/0.5×100=0.36%
Downsizing of 64% was realized in comparison of individual components

Comparison of Occupied Area when 50 Inductors are used

Comparison of Occupied Area when 50 Inductors are used

Assuming that 50 inductors are used, the occupied area on the board can be reduced by as much as 25-9=16mm2
(Comparison of component parts excluding soldered portions)

Less Performance Deterioration with Downsized LQP03T_02

LQP03T_ 02 Series achieved High Q with a unique internal structure

The LQP03_02 achieved High Q with a unique internal electrode formation technology and high precision multilayer technology, compared to the same size multilayer inductors of other companies in the same industry.

Characteristics Comparison of 1005 mm (0402 inch) Size vs. 0603 mm (0201 inch) Size (10 nH)

The 0603 mm size LQP03_02 realized favorable Q characteristics even in comparisons with the one size larger 1005 mm size.
