Toroid Ferrite Core for FT240-43 Ferrite Choke Ring, 1 Pack

Key features

• Professional-Grade Performance for Ham Radio DIY: Engineered for amateur radio enthusiasts, this High-performance NiZn ferrite toroid corel is ideal for building high-performance HF Baluns, Ununs, and Common Mode Chokes for EFHW and dipole antennas. Electrically equivalent to Mix 43 with stable inductance (AL=1075 nH/N²), it effectively suppresses common-mode currents from 5-300MHz, ensuring clear signal transmission for your critical projects.
• Exceptional RFI/EMI Noise Elimination: Crafted from premium NiZn ferrite (µi≈800, AL=1075 nH/N²), this core excels at absorbing unwanted RF and EMI noise from 5 to 300MHz. Say goodbye to frustrating issues like laptop trackpad freeze, distorted audio, and erratic equipment behavior caused by RF interference, especially on lower HF bands.
• Optimized Design for Easy Winding & Durability: Features a standard FT240-43 form factor (OD 2.4"/61mm, ID 1.4"/35.5mm). The generous center hole easily accommodates multiple turns of RG-8, RG-213, or similar coax. Smooth, rounded edges protect wire jackets from nicks and cuts, ensuring your DIY build is safe and reliable
• Secure Packaging for Safe Arrival & Long-Term Reliability: We understand the importance of receiving an undamaged core. Each toroid is individually wrapped in protective material to prevent chips and cracks during transit. Packaged in an individual box,making it a reliable component for your antenna projects for years to come
• Versatile Applications & Professional Use: Widely used for HF antenna construction, power supply filtering, and industrial electronic equipment. IMPORTANT SAFETY INFORMATION: This is a large industrial magnetic core (2.4-inch diameter) intended for professional and amateur radio use by adults. It is NOT a toy. Keep away from children.
