Product Description
The Wurth Elektronik 74272131 is an openable snap ferrite sleeve from the STAR-TEC series, engineered for effective electromagnetic interference (EMI) suppression in cable systems. With a 7.5 mm aperture diameter, this sleeve allows precise clamping around cables and facilitates easy installation and removal thanks to its snap design.
Constructed from high-quality manganese zinc (MnZn) ferrite material, this sleeve offers impedance of 28 Ω at 25 MHz for robust EMI filtering performance. The STAR-TEC key technology provides an advanced internal security locking system, preventing unauthorized removal from the cable and ensuring reliable operation. One key is included in every packaging unit, supporting cable clamping protection and reusability, making it ideal for test and measurement environments or cables with difficult access.
The sleeve's openable design is practical for varied cable diameters and frequent testing or measurement setups. Its external dimensions are 40 mm in depth, 24 mm in width, and 20 mm in height, supporting neat cable management in laboratory, industrial, and commercial electronic applications. It is especially designed for use in low-frequency ranges from 300 kHz to 30 MHz and can suppress electronic ballasts, including neon tube circuits in the lighting industry.
The operating temperature range from -25 °C to +105 °C ensures versatility across environments. The product complies with REACH and RoHS standards, offering superior safety and regulatory conformity. Applications include cable systems in laboratory, industrial, lighting, and manufacturing setups, where EMI protection and secure cable assembly are essential. The sleeve is reusable due to its unique locking technology and is perfect for test and measuring purposes.
