描述 Description

The SMP100LC is a series of low capacitance transient surge arrestors designed for the protection of high data rate communication equipment. The low capacitance of the devices avoids any distortion of the signal and is compatible with digital transmission line cards (xDSL, ISDN...).

SMP100LC series tested and confirmed compatible with Cooper Bussmann Telecom Circuit Protector TCP 1.25A.

The SMP100LC-xxx with the fuse TCP1.25A or TCP2A is compliant with Telcordia GR1089 (lightning and AC power fault tests), ITU-T K20/K21 (lightning and AC power fault tests), TIA/EIA-IS-968 (formerly FCC Part 68 lightning tests), and UL60950 (AC power fault tests). The use of the TCP1.25A allows the SMP100LC-xxx to be safe for the 2nd level (B criteria) AC power fault tests.

簡(jiǎn)介

SMP100LC屬于電路保護(hù)的TVS-晶閘管。由制造生產(chǎn)的SMP100LCTVS - 晶閘管基于晶閘管的瞬態(tài)電壓抑制 (TVS) 器件可用于提供過(guò)壓保護(hù)，在正常工作條件下近似于開(kāi)路。在這些器件兩端施加超過(guò)某個(gè)特定值的電壓（稱(chēng)為擊穿電壓），可使它們進(jìn)入近似于短路的導(dǎo)通狀態(tài)。?這種狀態(tài)一直持續(xù)至流過(guò)器件的電流因電路中的一些外部影響而降低到稱(chēng)為“保持電流”的最小值以下。
