Description

GDT circuit protection devices dissipate electrical surge energy safely within a contained plasma gas. Commonly used to help protect sensitive telecom and networking equipment and lines, GDTs protect from damage that may result from lightning strikes and equipment switching operations.

The Littelfuse GDT series described in this document are available in a variety of leaded and surface mount forms and offered with and without optional fail safe clip. Please refer to the electrical specifications, dimension and packaging options section of this document for additional information.

SL1021B250屬于電路保護(hù) > 氣體放電管避雷器（GDT）。力特公司制造生產(chǎn)的SL1021B250氣體放電管避雷器（GDT）氣體放電管或 GDT 是一種密封的玻璃封閉式器件，兩個(gè)電極之間注入了惰性氣體混合物。當(dāng)電壓超過 GDT 的額定值時(shí)，增加的電壓會(huì)使氣體電離，從而使其導(dǎo)電并將多余的電壓轉(zhuǎn)移到地下。
