Core advantages of Surface mount inductor

1. The iron powder core distributed air gap design features high saturation flux, slow inductance attenuation under large DC current, and superior performance compared to ferrite cores in high bias power circuits.
2. The magnetic field is enclosed within the magnetic ring, with minimal electromagnetic radiation outward, reducing interference to surrounding components and improving the overall EMI.
3. The inductance, copper wire diameter, number of turns, insulation coating / heat shrink tubing can all be adjusted as needed; tolerances can be selected as ±5% or ±10%.
4. When a window is allowed, thick copper wires can be used to reduce DCR, reduce copper loss, and improve power efficiency.
5. The size of the magnetic ring is compact, suitable for small adapters, LED drivers, and other power boards with limited space.

Why choose us

Q: What material is the T44-26 magnetic ring inductor made of?
A: The core material is iron powder core, with a magnetic permeability of 26μ. It is commonly known as the yellow-white ring in the industry. It has no frame and is in a ring structure. The winding is made by wrapping enameled copper wire.

Q: What is the normal inductance range of T44-26?
A: The regular inductance is 5-80 μH, and the inductance is determined by the number of turns; the tolerance can be ±5% or ±10%.

Q: What is the rated current of T44-26?
A: Regular 1.5-4A; the current-carrying capacity depends on the copper wire diameter. The thicker the copper wire, the higher the rated current and the smaller the DCR (direct current resistance).

Q: What are the characteristics of the iron powder core T44-26 compared to the iron silicon aluminum magnetic ring?
A: The iron powder core has a higher saturation magnetic flux density and a wider applicable bandwidth for high-frequency; however, at the same frequency, the magnetic core loss is higher than that of iron silicon aluminum, making it more suitable for medium and high-frequency filtering and small-power energy storage, but not suitable for high-power PFC.

Q: Is the decrease in inductance under large DC current a fault?
A: It is not a fault; it is an inherent DC bias characteristic of the iron powder core. When selecting, sufficient DC bias margin needs to be reserved.
