三英電気工業 List of Products and Services

Our company possesses the design and manufacturing technology for high-frequency coaxial connectors, which involves the design and assembly of connectors for coaxial cables that connect communication devices and antennas. It is essential to have the technology to design connectors that do not compromise the performance of the cables, and leveraging this expertise has enabled us to achieve miniaturization of coaxial termination resistors and lightning protectors for base stations. Currently, we are engaged in OEM production for major cable manufacturers and supplying to telecommunications companies. As the demand expands with the development and market proliferation of high-speed communication technology, we are proactively working on new product development by introducing equipment to analyze frequency characteristics. *For more details, please refer to the PDF document or feel free to contact us.*

We have made a model change to the coaxial arrester (lightning protector) for mobile base stations that we have been supplying as an OEM for many years to our valued customer, Mr. F. The issues identified include the need for further cost reduction compared to the existing model and the realization of wideband specifications. In response, we initiated a design aimed at miniaturization, cost reduction, and the coexistence of high-frequency characteristics. As a result, material costs were reduced due to the miniaturization of components such as the body. At the same time, plating and transportation costs were also reduced. Thanks to adjustments made by our technical team, the specifications now allow for stable coverage of wideband frequencies. [Issues] - Further cost reduction compared to the existing model - Realization of wideband specifications - The existing model has a thick size due to design considerations *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of the terminal resistor (5W) for mobile communication base stations deployed by Company B. The issues identified were the limited space available for use, the need for cost reduction in consideration of competing products, and the heat generated due to the maximum power usage of 5W. In response, we focused on miniaturization and cost reduction, specifically looking at the resistor and heat dissipation fins. As a result, we were able to maintain the high-frequency characteristics required by the customer even with a smaller structure for the heat dissipation fins, and by reducing material costs through miniaturization, we achieved a balance between cost reduction and performance. [Issues] - Limited space available for use - Measures for heat generated due to maximum power usage of 5W - Cost reduction in consideration of competing products *For more details, please refer to the PDF document or feel free to contact us.
