HIGH-SPEED, HIGH-CURRENT SURGE PROTECTORS 549

DESCRIPTION

www.cpclare.com PMT/UMT (275) Series CP Clare’s PMT(275) and UMT(275) Series surge protectors (350-500V and 550-2500V respectively) provide a high level of protection from high-speed, high-current transient surges. These devices are constructed using a proprietary semiconductor junction process which results in nanosecond response times combined with peak current ratings in excess of 20kA. n Fast impulse breakdown (≤125% of typical DC breakdown at 5kV/µs) n Tight DC breakdown voltage tolerance (±10%) n Low capacitance n Test equipment n Video displays n Medical electronics n Instrumentation circuits Series DC Breakdown Unit Voltage (typ) PMT(275) 350 V 400 V 450 V 500 V UMT(275) 550 V 600 V 650 V 750 V 800 V 850 V 1.0 kV 1.5 kV 2.0 kV 2.5 kV (See detailed specifications for more information.)
