Core advantages of Inductor

1. The iron-silicon-aluminum magnetic core is equipped with built-in air gaps. Under DC high current conditions, the inductance decays gradually, and it is less prone to saturation compared to ferrite magnetic cores.
2. The magnetic field is mainly confined within the magnetic ring, with little leakage outward, reducing electromagnetic interference to surrounding components and facilitating EMI debugging of the entire device.
3. The ferrosiliconaluminum material has a high Curie temperature, and its magnetic performance shows minimal attenuation under continuous full-load operation, with stable temperature rise performance.
4. When the window is allowed, a thicker enameled copper wire can be selected to reduce the DC resistance, decrease copper loss, improve power conversion efficiency, and reduce heat generation.
5. The body is compact, suitable for small adapters, LED power supplies, and compact power boards, enabling the realization of power inductance function in limited space.

 

 

Flowchart

Why choose us

Q: What material is the T044-125 magnetic ring inductor made of?
A: The core material is iron-silicon-aluminum Sendust magnetic powder core, with a magnetic permeability of 125 μ, without a frame, and the winding is made by wrapping enameled copper wire.

Q: What is the rated current of T044-125?
A: Standard 2-5A; The actual current-carrying capacity depends on the diameter of the copper wire. The thicker the copper wire, the higher the rated current, and the smaller the DCR (DC Resistance).

Q: What is the applicable working frequency range for T044-125?
A: It is applicable from 10kHz to 500kHz. When the frequency exceeds 500kHz, the core loss significantly increases, and it is not recommended for use in ultra-high frequency circuits.

Q: Is the decrease in T044-125 inductance under large DC a fault?
A: It is not a fault; it is an inherent DC bias characteristic of the iron-silicon-aluminum magnetic powder core; sufficient bias margin needs to be reserved during selection.

Q: What is the reason for the excessive temperature rise of T044-125 during operation?
A: Common factors: Insufficient wire diameter of copper wire, excessive DCR (Drift Current Resistance), actual working current exceeding the rated value, excessively high working frequency, significant core loss, and insufficient cooling due to overwinding of the window.
