大同電氣工業 List of Products and Services

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.

We would like to introduce our "Toroidal Transformers." Using "wound iron cores" as transformers for miniaturization and weight reduction of equipment is a good utilization method that takes advantage of the properties of magnetic materials. Recently, the performance of magnetic materials has significantly improved in terms of high magnetic flux density and low loss. By effectively using these advanced magnetic materials, we can achieve a reduction of over 40% in volume and more than 30% in weight compared to conventional cut-core transformers. This transformer is highly promising for miniaturization and weight reduction of equipment. 【Features】 ■ Compact and lightweight (volume and weight are less than 2/3 of cut-core types) ■ Slim design allows for mounting on printed circuit boards ■ Minimal leakage flux *For more details, please refer to the PDF document or feel free to contact us.
