Nickel‑Zinc Ferrite Anti‑Interference Core Ring (Toroid) 🔇📶

Reduce high‑frequency noise in power and signal lines with this compact nickel‑zinc (NiZn) ferrite toroidal core. Ideal for EMI/RFI suppression in Arduino and Raspberry Pi projects, as well as other electronics components and modules, this ring core helps clean up noisy voltage rails, data links, and motor leads. Made from environmentally friendly material and supplied in a convenient, easy‑to‑use form factor.

Key Features ✅

• Nickel‑zinc ferrite (NiZn) for effective high‑frequency interference attenuation
• Non‑magnetized core (not a permanent magnet) — safe around sensitive microcontroller circuits
• Compact toroidal form factor for slip‑on cable integration
• Works well on low‑voltage DC power and signal lines
• Great for Arduino, Raspberry Pi, sensors, motor drivers, and RF‑sensitive modules ⚙️
• Increase suppression by looping the wire through the core multiple turns

Technical Specifications 📐

• Material: Environmental protection material (nickel‑zinc ferrite, NiZn)
• Form Factor: Toroidal core (ferrite ring)
• Outer Diameter (OD): 12.0 mm (≈ 0.472 in)
• Inner Diameter (ID): 7.3 mm (≈ 0.287 in)
• Height: 20.0 mm (≈ 0.787 in)
• Magnetization: Non‑magnetized; not a strong magnet

Typical Applications 🔧

• Noise suppression on DC power leads for Arduino and Raspberry Pi boards
• Filtering of signal cables (I2C, SPI, UART), sensor wiring, and PWM/motor lines
• EMI cleanup on switching power supplies, DC‑DC converter inputs/outputs, and LED driver lines
• General electronics components and modules where high‑frequency interference is a concern

Usage Notes 📝

• Place the core as close as practical to the noise source or entry point
• For higher attenuation, pass the cable through the core multiple times (add turns)
• Fits single cables up to approximately 7.0 mm outer diameter (or multiple smaller wires)
• Ferrite is rigid and brittle — avoid mechanical shock or over‑tight clamping
• This is a ferrite core, not a permanent magnet

Whether you are building a precise microcontroller system or prototyping with Arduino and Raspberry Pi, this ferrite ring core is a reliable, cost‑effective way to mitigate EMI and improve signal integrity across your electronics modules and low‑voltage lines.
