High Flux Kool Mu Core Iron Power C Core Product Description

High Flux Kool Mu Core feature

High Saturation Magnetic Flux Density:

Its saturation magnetic induction can reach 1.5T~1.6T, much higher than that of ferrite (about 0.5T) and some amorphous alloys. It can withstand larger currents under the same volume, supporting high-power density design (e.g., reducing power supply volume by more than 30%).

 

Low Hysteresis and Eddy Current Loss:

After special annealing treatment, the alloy has a more uniform magnetic domain structure. In medium-to-high frequency (1kHz~50kHz) scenarios, its hysteresis loss is 20%~30% lower than that of ordinary iron-nickel alloys, and eddy current loss is well-controlled, reducing heat generation during equipment operation.

 

Strong DC Bias Capability:

Under working conditions with superimposed DC magnetic fields (e.g., inductors in switching power supplies), the magnetic permeability decays slightly. It can maintain stable magnetic properties, avoiding core saturation caused by DC bias, and is suitable for scenarios such as high-current filtering and energy storage.

 

Core Advantages of the C-Shaped Structure

Compared with toroidal, rectangular, and other structures, the C-shaped structure offers better practicality for power applications:

High Winding Convenience: The C-shaped core is divided into two symmetrical half-cores. Coils can be wound separately on each half-core before splicing and assembling. Unlike toroidal cores, there is no need to thread windings from one end of the strip, which greatly simplifies the winding process for high-turn, thick-wire coils and improves production efficiency.

 

Good Magnetic Circuit Controllability: An air gap can be accurately reserved at the splicing joint (air gap thickness adjusted according to requirements), flexibly regulating the core's magnetic resistance and inductance. This adapts to the design of magnetic elements with different powers and working conditions (e.g., high-frequency transformers, high-power inductors).

 

Excellent Heat Dissipation Performance: The open design of the C-shaped structure provides better heat dissipation than the closed toroidal structure. Additionally, the windings are in more uniform contact with the core, allowing heat to be quickly conducted to the housing, making it suitable for high-power equipment operating for long periods.

 

Iron Power C Core Application 

• Industrial Power Supply Field: Used in main inductors and transformers of high-power switching power supplies and uninterruptible power supplies (UPS). It adapts to high-current input and output, and improves power conversion efficiency (up to over 95%) relying on its low-loss characteristic.

 

• New Energy Field: Such as high-voltage power distribution units (PDU) of new energy vehicles and bidirectional converters of energy storage systems. It resists DC bias interference and ensures stable magnetic properties during frequent charging and discharging switching.

 

• Special Power Equipment Field: Used in special equipment such as high-frequency welding power supplies and laser power supplies. Under high-power and high-frequency working conditions, it balances low loss and structural convenience, meeting the compact design needs of equipment.
