28F Series

SMT Ferrite Bead Assembly

Product Description

Laird's 28F Series ferrite bead on wire products provide economical EMI filtering of differential mode noise in surface mount applications. They are designed to provide high frequency suppression of differential mode EMI noise on groups of data/power lines. It is rated up to 10 amperes per filtered channel. Their rugged construction provides superior protection against transient events as well as much higher peak current handling capability than other EMI suppression devices.
