Ferrite Sleeves

In stock

A range of solid and split Ferrite Sleeves, which can be used as suppression cores and shielding beads for round cables. They are available for a wide range of cable diameters.

Split Ferrite Sleeves (or cores) are clamp type sleeve that are used as suppression cores. They feature A5 material cores that are installed around a cable. They are ideal for making estimations in EMI precaution and attenuate any form of EMI emission. The polyamide case simplifies assembly of the core in equipment, where retrofit and testing is a necessity. The high performance magnetic material allows for protection from unwanted EMI radiation , without affecting the wave forms, in digital equipment. They can be used for personal computers, word processors, fax machines, display equipment, photocopiers, and computer consoles. This protection ensures immunity against transmission and other types of noise in such equipment, which is essential. They can be mounted on to both a cable with a connector and a wired harness. They binding band ensures the cable is securely fixed.

Solid Ferrite Sleeves are a broad selection of shielding beads that guarantee impedance specifications over a wide frequency range. This range includes options that are mainly applied to wire assemblies and the MATV CATV industries. The range also includes options with a ring configuration that provides greater utilisation of the ferrite material properties, which can be used for a wide frequency range and are mainly used as multi-turn suppression cores.

  • Ferrite Materials: A5, 3A5, G7 and K5B
  • Casing Material: Polyamide 6.6 (PA)
  • Colour: Black
  • UL94 V0 Flame Rated
