Our "LFA34" series chip type LC EMI filter array is an extremely efficient EMI filter made of a combination of both dielectric and magnetic materials.It is a 3 terminal array of 4 LC ladder circuits in a 1206 package, suitable for noise reduction on high frequency signal lines, due to steep and wide-band insertion loss characteristics.
■ Features
• Monolithic construction of dielectric and magnetic materials.
• 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.
■ Applications
• For digital AV equipment and other digital circuit equipment.
