Murata's high inductance, high Q chip inductors help miniaturise FM circuits
Murata's LQW21H series of chip inductors maintains high Q of at least 35 in the FM band,whilst offering high inductance and small size. It enables designers working with FM circuits to miniaturise their designs without compromising on performance. This series is designed for any FM band application where board space is critical, for example, TV tuners for mobile devices.
Available in compact 0805 packaging, the LQW21H series provides 0.47 to 2.2uH inductance. The 0.47uH part, LQW21HNR47J00, has a rated current of 160mA at 10MHz with a maximum 1.30 Ohm DC resistance. The highest inductance part in the series is the LQW21HN2R2J00, with inductance 2.2uH at 10MHz, rated current of 75mA and a DC resistance of 6.5 Ohms maximum.
Minimum Q is 35 at 100MHz for all parts in the series, with typical figures above 50 at the same frequency.
