Product Description
The Wurth Elektronik 74272221 is an openable snap ferrite sleeve engineered for the suppression of electromagnetic interference (EMI) in cable and wire assemblies. Featuring a patented STAR-TEC key locking system, this sleeve securely mounts to cables and allows for easy installation and removal, making it especially suitable for environments where cables are tested or routinely accessed.
The 10.5mm aperture diameter is compatible with a wide variety of cable types, offering flexible utility for engineers and technicians. The manganese zinc (MnZn) ferrite material provides excellent noise attenuation properties, with an impedance of 35 Ohm at 25 MHz and 140 Ohm at 100 MHz. This performance makes it particularly effective for suppressing unwanted signals in the frequency range of 300 kHz to 30 MHz, which is common in test and measurement, lighting, and general industrial applications.
The external sleeve dimensions are 41.6 mm in depth, 33.5 mm in width, and 28.4 mm in height, enabling installation even within constrained spaces. The openable, reusable design enables easy servicing of cables, repeated adaptation and re-use for both permanent and temporary set-ups, and is ideal for troubleshooting or temporary EMI reduction during experiments and diagnostics.
Compliant with RoHS and REACH standards, the 74272221 ferrite sleeve assures the user of environmentally responsible material use. Its robust core and internal security locking prevent accidental removal or tampering, ensuring ongoing EMI protection. Additional features include cable clamping protection and a non-gapped ferrite core for consistent impedance characteristics.
This ferrite sleeve is commonly used in industrial control panels and electronics, power distribution equipment, laboratory test benches, lighting systems (including suppression of electronic ballasts), and any application where EMI compliance is critical. Its reliable design makes it an excellent choice for designers, test engineers, installers, and maintenance technicians seeking repeatable and assured EMI filtering on-site or in permanent installations.
