The Iron-silicon-aluminum Magnetic Ring Coil Differential Inductor is made by pressing and sintering iron-silicon-aluminum ternary soft magnetic alloy powder. It is the core performance carrier of the component. Iron-silicon-aluminum alloy combines the high saturation flux density of iron powder core and the low loss characteristics of ferrite. Its magnetic permeability is stable and the temperature coefficient is low, ensuring the stability of inductance value within a wide temperature and frequency range. The magnetic ring is a closed structure, which can maximize the magnetic field concentration, reduce magnetic leakage, and minimize electromagnetic interference to surrounding components.
It uses high-purity oxygen-free enameled copper wire. The winding is uniformly and densely wound on the surface of the magnetic ring, and the two ends of the winding are led out to symmetrical connection terminals. When current flows from one end and out from the other end, a closed magnetic circuit is formed inside the magnetic ring, presenting a high impedance to common-mode interference signals (the same-direction noise between the phase wire and the neutral wire), and having an extremely small impedance to direct current or low-frequency current, achieving the function of "allowing direct current to pass through, blocking common-mode AC". The wire diameter and the number of turns are precisely designed according to the target inductance value and the rated current requirement.
No noise is generated when operating at different frequencies; excellent DC biasing capability with good stability.
The saturation magnetic flux density of the iron-silicon-aluminum magnetic core can reach 1.05T, which is higher than that of ordinary manganese-zinc ferrite. It has excellent anti-dc bias performance. Under the condition of large current direct current stacking processing, the inductance value will not drop sharply, making it suitable for power supply systems with large current such as charging piles and inverters.
Iron-silicon-aluminum Magnetic Ring Coil Differential Inductor's working frequency range is 8 kHz to 1 MHz. The core loss is low, effectively reducing the temperature rise of the components and improving the energy conversion efficiency of the circuit.
The magnetic permeability coefficient of the iron-silicon-aluminum magnetic core is low. Within the wide temperature range of -40℃ to +125℃, the variation rate of inductance value is less than ±10%, making it suitable for harsh temperature environments such as industrial-grade and automotive-grade.
The closed magnetic ring structure significantly reduces magnetic field radiation. Compared to the open-shaped I-beam inductor, it causes less interference to surrounding sensitive components and does not require additional shielding covers, simplifying the circuit layout.
The alloy magnetic core is resistant to vibration and corrosion. The winding is closely integrated with the magnetic core, without any risk of loosening. It can operate stably for a long time in high-vibration and high-humidity environments.
The outer diameter ranges from 6mm to 60mm.
