(1/3) Common Mode Filters(SMD) For Power Line ACM Series ACM3225, 4532, 7060, 9070, 1211, 1513 Types FEATURES • A chip-type common mode filter for large current applications. Common mode impedance surpasses 300 to 1000Ω at 100MHz. Noise is greatly suppressed. • Capable of handling the highest current (up to 10A) of any chiptype common mode filter. • Height and size have been considered, resulting in a compact and light-weight choke coil. Applicable for the miniaturization required to reduce the size and weight of portable equipment. • The products contain no lead and also support lead-free soldering. • This product does not contain regulated substances that are slated to be included in RoHS. APPLICATIONS Used for power line noise suppression for any electronic devices. Used to [ ... ]
