EMI countermeasure ferrite core

EMI countermeasure ferrite core

Due to its non-conductive nature, insulation treatment is unnecessary, making it highly cost-effective!

We would like to introduce our "EMI Countermeasure Ferrite Core." Due to its non-conductive nature, insulation treatment is unnecessary. It offers excellent cost performance. Additionally, because of its characteristics suitable for high-frequency applications, it is used as an EMC countermeasure material for terminal noise suppression in the 10MHz to 30MHz range and for a wide range of high-frequency unwanted radiation countermeasures from 30MHz to 500MHz, across various fields. 【Features】 ■ No insulation treatment required due to non-conductive nature ■ Excellent cost performance ■ Characteristics suitable for high-frequency applications ■ Used in a wide range of fields as an EMC countermeasure material for terminal noise suppression and high-frequency unwanted radiation countermeasures *For more details, please refer to the PDF document or feel free to contact us.

Ferrite core for converter transformer PQ107/87/70

Ferrite core for converter transformer PQ107/87/70

Ferrite core with proven performance in V2H converter transformers.

V2X refers to the concept of utilizing the power from the onboard batteries of EVs (Electric Vehicles) and PHEVs (Plug-in Hybrid Electric Vehicles) for purposes other than vehicle operation. "V2X" is a collective term that includes V2L (Vehicle to Load), V2H (Vehicle to Home), and V2G (Vehicle to Grid). V2H (Vehicle to Home) is a system that connects vehicles and homes using a bidirectional charging system. It is expected to reduce electricity costs and ensure a power source during disasters. Large ferrite cores are used in the converter transformers employed in this system.

GAP processing ferrite core

GAP processing ferrite core

The sizes of available ferrite cores vary! Such as "EP13," "EP17," "RM6," "RM8," "RM10," "RM12," "Q25/19," etc.

Daido Electric Industry is currently offering ferrite cores with GAP processing! We have newly introduced a GAP processing machine that was also used by ferrite core manufacturing manufacturers. One method to adjust the characteristics of coils using ferrite cores is to shave the core's middle foot, which is commonly referred to as "gap processing." Until now, Daido Electric Industry has been performing gap processing manually, but by introducing the GAP processing machine, we have been able to reduce the working time to about one-third of the conventional time, and the processing accuracy has significantly improved. For high-precision ferrite cores with gap processing delivered in a short time, please leave it to us. 【Currently available sizes of ferrite cores】 "EP13" "EP17" "RM6" "RM8" "RM10" "RM12" "Q25/19" "Q30/22" "Q40/29" "P30/19" "P36/22" "P45/29" "P59/36" *More sizes are expected to be added in the future. *For more details, please refer to the PDF document or feel free to contact us.

Electricity Bill Reduction Solution "Power Guard"

Electricity Bill Reduction Solution "Power Guard"

Cutting the "harmonics," which are the cause of power loss, and reducing electricity costs! 'Power Guard'

Are you consuming more power than necessary? Various places that use electricity generate electrical noise called harmonics, which disrupts the flow of electricity and leads to losses in electricity costs. Power Guard has been developed by changing the metal composition and manufacturing methods of conventional ferrite cores to specifically reduce the harmonics that directly contribute to power loss. As a product specialized in harmonic suppression, it is currently pending utility model/patent application. *Please note that this product will be sold after a practical demonstration (for a fee) is conducted.
