The "inductor coil" is applied in the following industries: new energy and energy storage, automotive electronics and electrification, industrial automation and power supply, information and communication technology, consumer electronics and household appliances; its application locations include: the energy storage and output filtering positions of DC-DC circuits, the common-mode/differential-mode choke coil positions at the power input end, the transmitting and receiving coils of wireless charging devices, and the matching network and bias circuit of RF power amplifiers; its application under working conditions includes: high current, strong magnetic field, and high temperature.
The Choke Coil Iron Powder Core Differential Inductor is an inductive component specifically designed to suppress differential-mode interference in circuits. The core is made of iron powder, serving as the magnetic path carrier. Thanks to the excellent magnetic properties and structural design of the iron powder, it can form a high-impedance barrier against the differential-mode interference signals between the phase line and the neutral line. It is widely used in the electromagnetic compatibility (EMC) rectification and signal filtering scenarios of power supply systems.
The core body of the magnetic core is made by pressing and sintering carbonyl iron powder. By adjusting the particle size of the iron powder, the insulation coating, and the pressing density, the parameters such as magnetic permeability and saturation magnetic flux density can be precisely controlled. Compared with ferrite magnetic cores, the iron powder core has a higher saturation magnetic flux density and a wider operating temperature range. Moreover, it has lower core loss in the medium and high frequency bands and is suitable for scenarios of large current differential mode suppression. Common shapes include ring-shaped, I-shaped, and can-shaped, which are suitable for different installation and circuit requirements.
The differential mode winding coil is made by winding high-purity oxygen-free enameled copper wire. The single-winding symmetrical design is the core feature of the differential mode inductance. The terminals at both ends of the coil are connected to the terminals. The current flows in one end and out from the other end. The magnetic field forms a closed loop inside the magnetic core, presenting a high impedance to the differential mode current and having an extremely low impedance to DC or low-frequency current. The wire diameter and the number of turns are precisely matched according to the inductance value and the rated current requirements.
Precise differential-mode interference suppression
Choke Coil Iron Powder Core Differential Inductor is designed specifically for differential-mode interference, it presents a high impedance in the interference frequency range, effectively attenuating differential-mode noise and preventing the transmission of interference signals, helping the equipment pass the EMC certification.
High saturation current carrying capacity
The saturation magnetic flux density of the iron powder core can reach above 1.5T, which is higher than that of ordinary ferrite cores. It is less likely to experience magnetic saturation under large current conditions, and the inductance value remains stable. It is suitable for large current scenarios such as new energy charging piles, photovoltaic inverters, industrial power supplies, etc.
Broadband low-loss characteristics
The working frequency range covers a wide band from 1kHz to 1MHz. The core loss is lower than that of the same specification ferrite inductor. The energy conversion efficiency is higher, which can effectively reduce the component temperature rise and improve the circuit stability.
High anti-electromagnetic interference capability
The closed or semi-closed magnetic circuit design significantly reduces magnetic leakage. Compared to the open-shaped I-beam inductor, it has less electromagnetic radiation impact on surrounding sensitive components, and no additional shielding measures are required.
Excellent environmental adaptability
Wide working temperature range (-40℃ to +125℃), resistant to vibration and corrosion, complies with environmental protection standards such as RoHS and REACH, suitable for harsh application environments such as industrial and automotive-grade.
