Description

Split Core Ferrite 0443164151 is a round, split-core (snap-on) ferrite suppression assembly, designed to clamp around cables or wire bundles. It is engineered for common-mode EMI (electromagnetic interference) suppression across the 25 MHz to 300 MHz band, making it suitable for signal-line filtering, noise mitigation, and EMI control in communication, networking, and electronics systems.

 

Key Features & Specifications

  • Cable / Bundle Capacity: Designed for up to 12.7 mm diameter cable or bundle.
  • Impedance: Rated 250 Ω (typical at specified frequencies) for common-mode suppression.
  • Frequency Range: Specified for use from 25 MHz to 300 MHz in suppression applications.
  • Construction: Snap-It™ (split/hinged) design with two halves that clamp around existing cable runs (no need to cut or thread the cable).
  • Material / Core Type: Uses Fair-Rite “43 material” ferrite (a NiZn formulation optimized for suppression in this frequency band)
  • Casing: Enclosed in a polypropylene housing rated UL 94 V-0 (flame retardant) and RoHS-compliant.
  • Dimensions: Approximate outer dimensions: 29 mm × 14.8 mm; length ~32.5 mm; inner (ID) ~12.75 mm.
  • Weight: ~84 g per unit.

 

Applications & Use Cases

  • EMI / RFI Filtering: Suppresses common-mode noise on cables in electronics, communications, and networking gear
  • Retrofit / Field Use: The snap-on design allows adding it to existing installations without disassembly
  • Signal / Data Lines: Particularly useful for cable runs carrying sensitive high-speed or RF signals
  • Compliance / Certification: Helps systems meet EMC/EMI standards by attenuating interference

Benefits

  • Non-intrusive installation — can be clipped onto existing cable paths
  • Broadband suppression — effective across 25–300 MHz
  • Durable & safe — flame-retardant casing and RoHS compliance
  • Compact form factor — ideal for constrained or retrofit environments
