Pinça de núcleo de ferrite DELOCK 80947, preto, 36×19,5×18 mm, pack de 2

DELOCK 80947 ferrite core clamp in black is a compact, clip-on EMI suppression component supplied as a pack of 2. Each clamp measures 36 × 19.5 × 18 mm and is made from a combination of nickel, plastic and zinc. The clamp is intended to be attached to round cables or cable bundles to absorb and dissipate high-frequency electromagnetic interference that may travel along the conductor, helping to improve signal integrity in electronic devices, networking equipment and power lines.

Advantages

The clamp-on ferrite cores provide targeted suppression of EMI without requiring changes to cable routing or connectors. Their compact dimensions make them suitable for use on desktop equipment and in confined installation spaces. Construction from nickel, plastic and zinc ensures mechanical stability and a secure clip fit on round cables. Supplied as a pack of two, the set allows attenuation at both ends or on multiple cables when needed.

Suitable for

• Reducing interference on data transmission cables and USB leads
• Suppressing noise on power lines and adapter cables
• Improving signal quality for electronic measurement and test equipment
• Installation in desktop computers, network devices and small office electronics

Key specifications

• Dimensions: 36 × 19.5 × 18 mm
• Quantity: pack of 2
• Colour: black
• Material: nickel, plastic and zinc
• Mounting: clip-on clamp for round cables and cable bundles

How to use

Open the clamp, position it around the cable or bundle where interference suppression is required and snap it closed so the ferrite core grips the cable. For higher attenuation, place one or more clamps close to the source of interference or at both ends of the cable. Ensure the clamp is fitted to round sections of the cable and avoid placing the clamp over connectors or insulating sleeves that prevent direct contact with the cable jacket.

Recommendations

Use the ferrite core clamp near noise sources such as power supplies, adapters or digital interfaces for the most effective suppression. When dealing with multi-conductor bundles, a clamp installed around the entire bundle will provide broader suppression; for critical signal lines, add clamps at multiple points along the cable. Do not attempt to open or modify the core materials, and avoid excessive mechanical stress during installation.
