About Sankosha U.S.A., Inc.
For over 75 years, we have developed and manufactured the Ceramic Gas Tube Surge Arrester (Gas Discharge Tube or GDT). Sankosha gas tube arresters protect personnel, equipment and circuitry from abnormally high voltages caused by lightning or electrical transients. Our surge protection devices have well defined surge-limiting characteristics enabling them to spark over (or breakdown) when the abnormal voltage on a line reaches a specific level. When sparkover occurs in the GDT, the surge is redirected to earth. Sankosha's gas tube arrestors are known for their quality.
Throughout the world, products from our factories provide protection for equipment and personnel. Sankosha has been selling gas tube arresters in the U.S. since the seventies and Sankosha U.S.A., Inc., the company's 100% owned subsidiary, was established in 1987 to better service the growing market in the Americas. We have a sales office in Torrance, CA, with headquarters in Japan and affiliates across Asia.
关于 Sankosha U.S.A., Inc.
超过75年来，我们一直致力于开发和制造陶瓷气体放电管（GDT）。Sankosha 气体放电管保护人员、设备和电路免受雷击或电瞬变引起的异常高压的影响。我们的浪涌保护装置具有明确的浪涌限制特性，当线路上的异常电压达到特定水平时，它们会产生火花放电（或击穿）。当 GDT 中发生火花放电时，浪涌将被重定向到大地。Sankosha 的气体放电管以其高品质而闻名。
我们的产品遍布全球，为设备和人员提供保护。Sankosha 自七十年代起在美国销售气体放电管，并于1987年成立了全资子公司 Sankosha U.S.A., Inc.，以更好地服务不断增长的美洲市场。我们在加利福尼亚州托伦斯设有销售办事处，总部设在日本，并在亚洲各地设有附属公司。
Acerca de Sankosha U.S.A., Inc.
Durante más de 75 años, hemos desarrollado y fabricado el descargador de sobretensiones de tubo de gas cerámico (tubo de descarga de gas o GDT). Los descargadores de tubo de gas de Sankosha protegen al personal, equipos y circuitos de voltajes anormalmente altos causados por rayos o transitorios eléctricos. Nuestros dispositivos de protección contra sobretensiones tienen características bien definidas que les permiten encenderse (o romperse) cuando el voltaje anormal en una línea alcanza un nivel específico. Cuando se produce el encendido en el GDT, la sobretensión se redirige a tierra. Los descargadores de tubo de gas de Sankosha son conocidos por su calidad.
En todo el mundo, los productos de nuestras fábricas proporcionan protección para equipos y personal. Sankosha ha estado vendiendo descargadores de tubo de gas en los EE. UU. desde los años setenta y Sankosha U.S.A., Inc., la subsidiaria de propiedad 100% de la compañía, se estableció en 1987 para atender mejor al creciente mercado en las Américas. Tenemos una oficina de ventas en Torrance, CA, con sede en Japón y filiales en Asia.
Our Products
Gas Discharge Tubes (GDTs)
Sankosha's gas discharge tubes are extremely durable and provide the industry's best impulse life specifications. They feature high surge ratings with very low capacitance and provide excellent response to fast rising transients. Sankosha gas discharge tubes are available in axial leaded, radial leaded, surface mount, and special packages. High voltage gas tube models like the Y08SV-312B are designed for power supply applications where HiPot testing is required, and we also manufacture very small gas tube arrester models for surface mount applications where real estate is at a premium. Sankosha's GDT's come in both two and three electrode configurations. Discharge voltages from 75V to 6000V are available.
Download DatasheetSAN-EARTH® Conductive Concrete
In the 1970's, Sankosha developed SAN-EARTH®, the original conductive concrete ground enhancement material. SAN-EARTH M5C is a fine powder used to build highly effective environmentally safe permanent grounding electrodes. SAN-EARTH M5C is manufactured in accordance with Sankosha's ISO 9001 Quality Standards and meets IEC Standard 62561-7. It offers many advantages over bentonite, remaining conductive whether wet or dry. One bag is enough to install a two-foot wide ten-foot long electrode, requiring less material than competing products.

Sankosha's RJ45 LAN SPDs provide reliable surge protection of GigE (1000Base-T), 100Base-TX, 10Base-T and Power Over Ethernet (PoE) equipment. All four compact Local Area Network modules are equipped with RJ45 Connectors and can be used as stand alone surge protection devices. They are also designed with integrated clips for easy installation on a standard 35mm DIN rail. The LAN-CAT5e-P complies with IEEE Standard 802.3af and with the direct lightning impulse 10/350µs 2.5kA waveform requirements of the Category D1 Test under IEC 61643-21.
Download DatasheetCoaxial Surge Protection Devices (SPDs)
Sankosha's Coaxial Surge Protection Devices (SPDs) provide heavy duty protection from surges caused by lightning or other transients. Radio and wireless telephone communication equipment is particularly vulnerable because antennas are typically located in areas where the probability of exposure to lightning related surges is high. Damage caused by direct strikes to the antenna itself or induced surges through the grounding system is prevented when coaxial protectors are in place. These SPDs are well suited for Broadband, CATV, GPS and cellular applications.

The Sankosha DWDM bandpass filter module has multiple modularized 50GHz and 100GHz DWDM filters and can be customized according to the customer's desired channel plan. WDM (Wavelength Division Multiplexing) is one of the optical communication technologies for transmitting a large-capacity signal. The DWDM can be mounted in a rack as a 1RU chassis. Various configurations are possible to meet individual customer requirements. The system is passive in nature with no power or cooling required. It is easy to install and requires no configuration or maintenance.
