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

 

Array of 4 LC filters, suitable for high density circuit lines.

 

Ultra miniature and low profile type

 

Steep insertion loss characteristics and removes noise over a wide range.

 

LFH24 series are smaller. (0804 size)

■ Applications

 For digital AV equipment and cellular phone.
