The T-20 Yellow Toroidal Ring Core (20×12×9.8 mm) is a versatile magnetic core designed to deliver high efficiency and low loss for custom wound power inductors and transformers. Featuring a compact and durable form factor, this ring core provides the stable magnetic field required for optimal inductive component functioning in modern electronic circuits.
Available at Tomson Electronics, this toroidal core is highly favored by hardware engineers for its excellent magnetic properties in tight spaces. It is specifically optimized for a wide range of low to medium power applications, making it an ideal foundational component for building efficient DC-DC converters, EMI filters, and custom energy storage chokes.

Q: What do the dimensions 20×12×9.8 mm mean?
A: These metric dimensions represent the physical size of the core. 20mm is the Outer Diameter (OD), 12mm is the Inner Diameter (hole size), and 9.8mm is the overall height (or thickness) of the ring.
Q: Can I use this core for high-frequency RF applications?
A: This specific core is tailored for power inductors and transformers (which typically operate at lower switching frequencies, like 50kHz to a few hundred kHz). For MHz-range RF applications, you would want a specific iron powder mix (like Mix 6 or Mix 2) designed for high-frequency, high-Q resonance.
