| HIGH-SPEED TRANSIENT SURGE PROTECTORS UNI-IMPS DESCRIPTION CP Clare's UNI-IMP high-speed transient surge protectors (0.55-20kV) provide the ultimate protection from highenergy, fast-rising transients such as Nuclear EMP. These devices are constructed using a proprietary semiconductor junction process that results in nanosecond response times combined with peak current ratings in excess of 20kA. A unique benefit of this technology is that the breakdown voltage is virtually independent of the rise time of the transient. In addition, the low capacitance of these devices allows for direct placement on highfrequency lines and antenna feeds without excessive loading.
