Radio Wave Anechoic Chamber To broadly respond to our customers' noise countermeasure requests, we have equipped a radio wave anechoic chamber and shielded room that comply with the 3-meter method as part of our headquarters' experimental facilities. We conduct electromagnetic interference measurements and countermeasures for various devices and systems, including not only our own products but also those from other companies, accumulating know-how for noise countermeasures. (Unwanted radiation measurements have been possible up to 6GHz since 2009.) We also perform immunity measurements and countermeasures for electrostatic discharge, lightning, and other factors.

E04RVA GPS Band Noise Countermeasure Components for GHz Band Released The GHz Band Ferrite Core "E04RVA" series is a noise countermeasure component designed for automotive devices, automotive harnesses, high-speed processing equipment, and high-speed communication cables that require noise countermeasures and EMS countermeasures in the GPS band (1.5GHz band). It enables noise countermeasures in the vicinity of 1GHz, which could only be addressed through board-level measures in the past, to be implemented as an add-on while maintaining convenience.

Noise Countermeasure Component: Split Dust Core Released The split dust core "E04SRR" series can address normal mode noise, which is a concern due to magnetic saturation caused by signal currents. It has excellent saturation resistance characteristics and can be used in devices with high currents, such as inverters and power electronics. Additionally, its split design allows for installation after wiring, making it easy to work with. A dust core is a magnetic core made by covering a powder of magnetic material composed of iron and silicon with an insulating coating and compressing it into a solid form. While conventional ferrite cores use magnetic materials primarily composed of iron oxide and are effective for common mode noise countermeasures, we have now added a dust core that is effective for normal mode noise countermeasures to our lineup.

Noise Countermeasure Components for Radio Noise Band Launch of Enhanced Noise Countermeasure Nano Crystal Core The enhanced noise countermeasure nano crystal core "E04RKH" series is a noise countermeasure component designed for automotive equipment and automotive harnesses that require noise countermeasures and EMS countermeasures in the radio noise band (1MHz band for AM radio and 100MHz band for FM radio). Compared to conventional ferrite cores and nano crystal cores, it improves the characteristics in the radio noise band and achieves miniaturization and weight reduction of the products.

Company information
Hoshia Electric has established itself as a top manufacturer in various business fields, including information display systems such as road information boards, industrial lighting known for its waterproof and explosion-proof features under the name "Water Pearl," tunnel lighting that began with the full-scale installation in the Kanmon Tunnel, and resin products represented by "Cutting Duct." As a new business, we started the electromagnetic noise countermeasure (EMC) product business in 1997 to address electromagnetic noise issues arising from digital devices. In the LED business, we successfully developed a blue light-emitting diode in April 2002 and a white light-emitting diode in December of the same year. Based on these technologies, we are actively expanding our business in the field of LED lighting fixtures, ranging from roads and tunnels to industrial lighting. On March 9, 2018, Hoshia Electric Co., Ltd. was listed on the First Section of the Tokyo Stock Exchange. In April 2022, we transitioned to the Tokyo Stock Exchange Standard Market. Moving forward, we will continue to leverage our unique creativity and technological capabilities cultivated over the years to develop even more innovative products and strive for business expansion.
