Our "LFA14, 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 0603, 0805 or 0804 package, suitable for noise reduction on high frequency signal lines, due to steep and wide-band insertion loss characteristics. LFA14, FA24 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.
