O05E.pdf 08.9.2 <strong>Chip</strong> <strong>Coils</strong> for High Frequency Horizontal Wire Wound Ferrite Type LQW21H_00 Series (0805 Size) LQW21H Series is wire-wound chip inductor which is based on Murata's original ferrite core and precise wound technology. The use of a high frequency ferrite core as winding bobbin enables small size, but high inductance (micro H order) and high Q at FM band. ■ Features 1. High inductance (0.47 to 2.2 micro H) for FM band 2. High Q value 3. Smaller size and higher performance than 2.5x2.0mm air core inductor contributes to the design of smaller or thinner equipment. ■ Dimensions 2.0±0.2 0.45±0.1 0.9±0.1 1.2±0.2 0.15±0.1 (in mm) 5 ■ Applications 1. TV tuner circuits of mobile phones 2. FM Transmitter circuits 3. Matching applications of FM band ■ Rated Value (p: packaging code) Part Number Inductance Test Frequency Rated Current Max. of DC Resistance Q (min.) Test Frequency Self Resonance Frequency (min.)
