Product List |
Ferrite power bar shaped magnetic core inductors are designed specifically for power processing applications, with ferrite material bar shaped magnetic cores as key components. This material has high magnetic permeability, which can effectively gather and guide magnetic fields, reduce magnetic flux leakage, and improve inductance performance. The winding is tightly wound on a rod-shaped magnetic core, and the number of turns and wire diameter can be adjusted according to different power requirements. This inductor performs excellently in power circuits, efficiently storing and releasing energy, assisting in stabilizing current, filtering, and power conversion. For example, in switching power supplies, it helps maintain stable output voltage and reduce ripple. Its structural design makes it more flexible in space utilization, suitable for circuits with specific requirements for spatial layout, and its relatively compact size and good heat dissipation characteristics make it an important component for ensuring stable power transmission and processing in various electronic devices, such as consumer electronics, industrial control equipment, etc.
1. High magnetic permeability and efficient magnetic performance
--Magnetic permeability characteristics: Using ferrite material as
the magnetic core, it has a high magnetic permeability. This
enables the inductor to generate a strong magnetic field in a
smaller volume, enhancing its electromagnetic induction capability.
Compared to other ordinary magnetic core materials, ferrite power
bar shaped magnetic core inductors can achieve higher inductance
values under the same winding turns and current conditions, which
helps to store and convert energy more efficiently.
--Energy conversion efficiency: High permeability magnetic cores
can effectively reduce energy loss during power conversion. For
example, in a switching power supply circuit, it can quickly
respond to changes in current, efficiently convert electrical
energy into magnetic energy and store it, and then release the
magnetic energy at the appropriate time to convert it into
electrical energy, providing stable power supply to the load and
improving the energy conversion efficiency of the entire power
system.
2. Good power processing capability
--High current carrying capacity: This inductor is designed to
handle higher power and can withstand larger currents. By selecting
the appropriate winding wire diameter and optimizing the magnetic
core structure, it is possible to effectively reduce wire
resistance and magnetic core losses, allowing for larger currents
to pass through without deteriorating inductance performance. This
makes it suitable for applications with high power requirements,
such as industrial power supplies, electric vehicle charging
equipment, etc.
--Stable power output: able to maintain stable performance during
power transmission and conversion processes. It can effectively
suppress current fluctuations and voltage ripples, ensuring the
stability of output power. For example, in some precision
electronic devices that require extremely high power stability,
ferrite power bar shaped magnetic core inductors can provide stable
DC power to ensure the normal operation of the equipment.
3. Compact structure and flexible layout
--Space advantage: The rod-shaped magnetic core structure is
relatively compact and has an advantage in occupying space compared
to other shapes of magnetic core inductors. This compact design
makes it suitable for layout on circuit boards with limited space,
especially for miniaturized and integrated electronic devices such
as smartphones, tablets, and internal power management modules.
--Layout flexibility: The rod-shaped shape makes the installation
of inductors on circuit boards more flexible. According to the
needs of circuit design, different methods such as axial
installation or radial installation can be used to facilitate
layout and combination with other electronic components, meeting
diverse circuit design requirements.
4. Excellent frequency characteristics
--High frequency application: It performs well in high-frequency
circuits and can effectively suppress high-frequency noise. Ferrite
materials have high magnetic loss characteristics for
high-frequency signals, which can convert high-frequency noise
energy into thermal energy and consume it, thereby playing a
filtering role. This makes it widely used in high-frequency
applications such as communication equipment and RF circuits,
helping to improve signal quality and anti-interference ability.
--Broadband adaptability: With a wide operating frequency range, it
can not only achieve stable inductance function in the low
frequency range, but also maintain good performance in the mid to
high frequency range. Whether in low-frequency power filtering or
high-frequency signal processing scenarios, it can play its due
role and provide reliable inductance support for circuits with
different frequency requirements.
Process Step | Description |
Magnetic Core Preparation | - Material Selection: Choose appropriate ferrite materials based on the inductor's intended application. For high - frequency power applications, ferrites with high initial permeability and low loss at high frequencies are preferred. |
- Powder Mixing: Blend ferrite powders with additives (such as oxides of manganese, zinc, nickel, etc.) in precise proportions. These additives can modify the magnetic properties of the ferrite, like adjusting the Curie temperature or magnetic permeability. | |
- Compression Molding: Use a die to compress the mixed powder into a rod - shaped pre - form. The pressure applied during this process affects the density and mechanical strength of the magnetic core. | |
- Sintering: Heat the pre - formed rod in a high - temperature furnace (usually around 1000 - 14 | |
Winding | - **Wire Selection: Select t |
- **WinWinding Method: The winding can be done | |
- **InsulaInsulation: After winding, an additional layer of insulation may be applied, such as wrapping with insulating tape or dipping in an insulating varnish. This step protects the winding from short - circuits and mechanical damage. | |
Termination and Assembly | - Lead Attachment: Attach leads to the winding for electrical connection. This can be done by soldering, welding, or crimping. The leads are usually made of copper or a copper - alloy with good electrical conductivity and solderability. |
- Mounting Structure (if applicable): If the inductor requires a specific mounting structure for installation on a PCB or other equipment, it is added at this stage. This could be a plastic bobbin or a metal clip for mechanical support and proper positioning. | |
Testing and Quality Control | - Inductance Measurement: Use an LCR meter to measure the inductance value of the inductor. The measurement is carried out at a specific frequency and test voltage to ensure that the inductance is within the specified tolerance range. |
- DC Resistance Testing: Measure the DC resistance of the winding using a digital multimeter or a dedicated resistance tester. High DC resistance can cause excessive power loss, so it must be within the acceptable limits. | |
- Insulation Resistance Testing: Check the insulation resistance between the winding and the magnetic core, as well as between different turns of the winding. This is done using an insulation resistance tester to ensure there are no short - circuits or leakage currents. | |
- Magnetic Saturation Testing: Apply a gradually increasing DC current to the inductor while monitoring the inductance. The inductor should not reach magnetic saturation (a significant drop in inductance) below the rated current. |
