TRISILFOR TELECOM EQUIPMENT PROTECTION
FEATURES Bidirectional crowbar protection Voltage range from 400V capacitance from 20pF 45pF leakage current Holding current: Repetitive peak pulse current: (10/1000µs) MAIN APPLICATIONS sensitive equipment requiring protection against lightning strikes power crossing. These devices dedicated central office protection they comply with most stressfull standards. Their Capacitances make them suitable ADSL. DESCRIPTION SMP100LC series capacitance transient surge arrestors designed protection high debit rate communication equipment. capacitance avoids distortion signal compatible with digital transmission line cards (xDSL, ISDN.). Compatible with Cooper Bussmann fuse: 1.25A. BENEFITS Trisils subject ageing provide fail safe mode short circuit better protection. They used help equipment meet main standards such UL60950, IEC950 C22.2 UL1459. They have UL94 approved resin. package JEDEC registered (DO-214AA). Trisils comply with following standards GR1089 Core, ITU-T-K20/K21, VDE0433, VDE0878, IEC61000-4-5 part
