Wurth Elektronik Openable, Diameter 21 mm Ferrite Sleeve, Apertures: 1 Key 56 mm 47 mm 43 mm, For EMI Suppression

This ferrite sleeve is an openable snap-type core designed to reduce electromagnetic interference on cable runs. It is manufactured from 4W620 material and intended for in-line suppression tasks where a removable ferrite core is required. The component is suitable for installation around single conductors to improve signal integrity in assemblies that demand detachable EMI suppression.

• 210Ω impedance at 25MHz for targeted low-frequency attenuation
• 335Ω impedance at 100MHz for higher-frequency noise reduction
• Single-aperture design for straightforward cable placement
• Openable snap form for Rapid installation and removal
• Conforms to RoHS and REACH for regulated material content

• Suitable as an EMI suppression sleeve for cables in electronic racks
• Can be used as a removable ferrite core for EMI shielding during testing
• Used with power and signal leads to act as a ferrite choke 210Ω @25MHz
• Ideal for retrofit noise mitigation using a snap ferrite core with a 21mm aperture

It uses a Snap-on ferrite clamp mechanism that secures around a single conductor via its split, openable body.

The central hole measures 21mm in diameter, allowing a single cable or small bundled conductors of comparable overall thickness.

The component is MADE from 4W620 ferrite material and meets RoHS and REACH substance requirements.

The outer dimensions are 56mm depth, 47mm height and 43mm width, informing required mounting clearance.
