28A Series

Broadband EMI Split / Snap-On Ferrite Cable Cores

Product Description

Unwanted noise can compromise your power and connection cables, leading to poor performance and malfunction over time. laird's versatile selection of ferrite cable cores resist this noise, creating impedance for problematic circuits. They can easily be fitted as a countermeasure without taking up too much space and compromising your product design and can reduce the cost and amount of overall shielding required to confine EMI within a product's enclosure.
