Magnetic Bar Inductors Rod Inductor Magnetic Rod Coil DC Filtering 1UH 1.5UH 2.2UH
1.Product Description
Designed for DC filtering, this series of magnetic bar inductors offers 1μH, 1.5μH and 2.2μH inductance values to accurately match different circuit requirements. Adopting high permeability magnetic rods as the core, together with the precision wound coil structure, they can effectively suppress high-frequency clutter and ripple interference in DC circuits, significantly improving the purity of the power supply and ensuring stable operation of the equipment. The low DC resistance (DCR) copper wire winding process reduces its own loss while realizing efficient energy transmission and storage, reduces circuit heating and improves system energy efficiency. Compact and lightweight design allows for easy integration into small electronic devices, such as power adapters, automotive electronic modules, communication devices, etc. Combined with moisture-resistant insulation and anti-electromagnetic interference characteristics, they can operate reliably in a wide range of temperature environments from - 40°C to + 85°C, providing a stable and efficient filtering and energy storage solution for DC circuits.
1. Precise filtering: 1μH, 1.5μH, 2.2μH inductance value, can flexibly match different circuit requirements, excellent suppression of high-frequency turbulence in the DC circuit, can reduce the ripple by more than 30%, and effectively improve the purity of the power supply.
2. High efficiency and low consumption: Winding with low DC resistance copper wires, with minimal energy loss, energy transfer efficiency is increased by 15%, reducing circuit heating, saving power and extending the service life of the equipment at the same time.
3. Strong environmental adaptation: -40°C to +85°C wide temperature operating range, combined with moisture-proof insulation process, can operate stably in harsh environments, such as high-temperature industrial workshops, cold outdoor scenes.
4. Compact and easy to integrate: compact and lightweight design, suitable for miniaturized electronic devices, such as cell phone chargers, car navigation devices, etc., easy to layout and installation, saving circuit board space.
5. Good anti-interference ability: Magnetic bar structure with special winding process, effectively shielding the external electromagnetic interference, while reducing its own electromagnetic radiation, to enhance the anti-interference performance of the circuit, to ensure stable signal transmission.
2.Performance Characteristics
| Parameter | Characteristics | Remarks |
| Inductance Range | 0.1μH – 100μH (Common: 1μH, 1.5μH, 2.2μH, 10μH, etc.) | Adjustable by turns ratio & core material. |
| DC Resistance (DCR) | Low (e.g., 0.01Ω – 0.5Ω) | Lower DCR = better efficiency, less heat. |
| Current Rating (Isat/Itemp) | High (1A – 20A+) depending on wire gauge & core. | Saturation current limits max DC bias. |
| Core Material | Ferrite (Mn-Zn/Ni-Zn) or Powdered Iron | High permeability, low core loss at high frequencies. |
| Frequency Range | 10kHz – 100MHz+ (Effective for switching noise suppression) | Best for DC-DC converters, SMPS, and EMI filtering. |
| Temperature Stability | ±5% to ±10% over operating temp. (-40°C to +125°C) | Stable performance in harsh environments. |
| Self-Resonant Frequency (SRF) | >10MHz – 100MHz (Depends on inductance & parasitic capacitance) | Avoid operation near SRF to prevent impedance drop. |
| Tolerance | ±10% or ±20% (Standard) | Tighter tolerances available for precision circuits. |
| Mechanical Size | Compact (e.g., 5mm x 10mm to 10mm x 30mm) | Axial or radial lead types for PCB mounting. |
