Iron Powder Core

Yellow White Toroid Core High Permeability Iron Powder Core

Yellow White Toroid Core High Permeability Iron Powder Core

Iron Powder cores are distributed air gap cores, with excellent inductance stability under both DC &AC conditions, high resistivity, low hysteresis & eddy current losses.

  • Product Detail

Iron powder cores are magnetic cores made from finely powdered iron particles, they are distributed air gap cores. The insulation between particles reduces eddy currents and associated losses. This construction results core with excellent inductance stability under both DC &AC conditions, high resistivity, low hysteresis & eddy current losses. Iron Powder Cores commonly used in inductors, transformers, and other electromagnetic devices in electrical and electronic field.

Types of powder core:

  • In High-frequency application:Carbonyl Iron Powder Cores Made from highly pure iron, those powdered iron core excellent magnetic properties.
  •  Not Ultra-high frequency field:Reduced Iron Powder Cores are less pure than carbonyl iron core, which cost is a high.
  • Special Types of Iron Powder Core Application:Sendust and Molypermalloy Powder (MPP) Cores, which include additional materials (e.g., silicon, aluminum, or molybdenum) to enhance certain properties such as permeability and saturation flux density.


Advantages

  • High Permeability: Iron powder cores have a high permeability, which allows them to effectively store and transfer magnetic energy.
  • Low Eddy Current Losses: The insulation between iron particles reduces eddy current losses, making them efficient at higher frequencies.
  • Cost-Effective: Compared to other core materials like ferrites, iron powder cores are often more cost-effective.
  • Versatility: They are available in various shapes and sizes, making them suitable for a wide range of applications.

Applications

  • Inductors: Used in power supplies, RF circuits, and audio equipment to store energy and filter signals.
  • Transformers: Suitable for small transformers, especially in high-frequency applications.
  • EMI Suppression: Used in electromagnetic interference (EMI) filters to reduce noise in electronic circuits.
  • Chokes: Employed in choke coils for DC-DC converters and other power supply applications.

 

Design

When selecting an iron powder core, consider the following factors:

  • Frequency Range: Ensure the core material is suitable for the operating frequency of your application.
  • Permeability: Choose a core with the appropriate permeability for your design requirements.
  • Saturation Flux Density: Ensure the core can handle the expected magnetic flux without saturating.
  • Loss Characteristics: Consider the core losses, especially if operating at high frequencies.
  • Size and Shape: Select a core that fits within the physical constraints of your design.

Iron powder cores are a versatile and widely used component in many electromagnetic applications, offering a balance of performance, cost, and availability.
