Our "LFA24, LFH24" series are extremely efficient EMI filter arrays with monolithic construction of inductor and capacitor elements.
They are 3 terminal arrays of 4 LC circuits in a 0805
or 0804 package, suitable for noise reduction on high
frequency signal lines, due to steep and wide-band insertion
loss characteristics. LFA24 and LFH24 series have distributed
element circuits.
■ Features
