Wurth Elektronik model 74271132 is an openable ferrite sleeve engineered to suppress electromagnetic interference (EMI) in industrial and electronic assemblies. This ferrite sleeve features an aperture diameter of 8.5 mm, designed to accommodate standard cable sizes for efficient inline noise reduction.
The sleeve is manufactured from 4W620 ferrite material, which provides magnetic consistency and reliable impedance performance. It exhibits an impedance of 125Ω at 25 MHz, optimizing low-frequency noise attenuation, while also achieving 235Ω impedance at 100 MHz to suppress mid-to-high frequency interference effectively.
The product’s openable design simplifies retrofit installation and maintenance by allowing the sleeve to be attached or removed without disconnecting cables, ideal for repair and servicing scenarios. The external dimensions are 36.3 mm in width, 24.2 mm depth, and 19.7 mm height, making it compact for integration in constrained spaces and control panels.
Compliant with REACH and RoHS environmental directives, this Ferrite Sleeve ensures adherence to critical sustainability and safety standards. It is manufactured in Italy, assuring rigorous quality control in production.
Applications include EMI noise reduction in power cables, control and signal wiring, retrofit ferrite installation in harnesses, and attenuation solutions in industrial electronic assemblies designed to improve electromagnetic compatibility (EMC) performance.
Constructed from 4W620 ferrite material for consistent magnetic properties. Offers 125Ω impedance at 25 MHz to reduce low-frequency electromagnetic interference. Provides 235Ω impedance at 100 MHz for effective mid-to-high frequency noise attenuation.
Openable design enables retrofit installation without cable disconnection. Compact outer dimensions of 36.3 mm width, 24.2 mm depth, and 19.7 mm height for easy panel integration. Complies with REACH and RoHS environmental standards for material safety.
Suitable for inline EMI suppression in power cables and control wiring applications. Made in Italy ensuring quality manufacturing standards. Explore more electronic components and EMI suppression products in the Electronics Components category on EnvMart.
