Trisilfor telecom equipment protection
Bidirectional crowbar protection Voltage range from capacitance from leakage current Holding current: Repetitive peak pulse current: (10/1000 (JEDEC DO-214AA)
Main applications
sensitive equipment requiring protection against lightning strikes power faults. These devices dedicated central office protection they comply with most stressfull standards. Their Capacitances make them suitable xDSL.
Description
SMP100LC series capacitance transient surge arrestors designed protection high data rate communication equipment. capacitance avoids distortion signal compatible with digital transmission line cards (xDSL, ISDN.). SMP100LC series tested confirmed compatible with Cooper Bussmann Telecom Circuit Protector 1.25A. SMP100LC-xxx with fuse TCP1.25A TCP2A compliant with Telcordia GR1089 (lightning power fault tests), ITU-T K20/K21 (lightning power fault tests), TIA/EIA-IS-968 (formely Part lightning tests), UL60950 power fault tests). Moreover, TCP1.25A allows SMP100LC-xxx safe level criteria) power fault tests.
