Ring Ferrite Core 27×14×11mm

The Ring Ferrite Core 27×14×11mm is a compact toroidal magnetic core made from ferrite material, designed to influence and control magnetic fields in electrical and electronic circuits. Ferrite is a ceramic-like magnetic material with high electrical resistance, which makes it ideal for minimizing unwanted eddy current losses at high frequencies. The toroidal or ring shape provides a closed magnetic path that enhances magnetic coupling and reduces magnetic leakage, making this core especially effective for inductive components and noise suppression.

In practical use, this ring ferrite core serves as the backbone of various inductive elements such as chokes, filters, and transformers. When wire is wound around the core or a conductor is passed through its center, the core increases inductance and helps filter out high-frequency interference from signals or power lines. Its physical dimensions an outer diameter of approximately 27 mm, an inner diameter near 14 mm, and a height of about 11 mm make it well-suited for DIY electronics, power supplies, and communication circuits where space is limited but electromagnetic performance matters.

The material and size balance electrical performance with mechanical robustness. Ferrite cores like this are inherently stable and resilient, capable of operating across a broad temperature range without significant changes in magnetic behavior. They are widely available and inexpensive, which makes them a go-to choice for both hobbyists and professional designers working on noise reduction, signal conditioning, or transformer design.
