Our "LFB30" series chip type LC EMI filter is an extremely efficient EMI filter made of a combination of both dielectric and magnetic materials. They have steep insertion loss characteristic,and high current rating (~1A) makes it well suited for reducing EMI noise on DC power lines.

■ Features

 Monolithic construction of dielectric and magnetic materials
 Steep insertion loss characteristics
 Removes noise over a wide range
 Easy to place since there is no polarity
 High current rating (~1A) makes it well suited for reducing EMI noise on DC power lines.

■ Applications

Noise reduction of DC power lines for computers, computer peripheral equipment, digital TV, cellular telephone, etc.
