HIGH-SPEED TRANSIENT SURGE PROTECTORS
UNI-IMPS
DESCRIPTION
STANDARD VOLTAGES
APPLICATIONS
FEATURES
CP Clare's UNI-IMP high-speed transient surge protectors (0.55-20kV) provide the ultimate protection from high-
energy, 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 high-
frequency lines and antenna feeds without excessive loading.

See specifications
tables
UNI-IMPS with other breakdown voltages in the 0.55 to 20kV range
are available on request. All UNI-IMPs are available with .360 O.D.
endcaps. UGTs are also available with .250 O.D. endcaps. UBDs are
available with a threaded male termination (#8-20) on one end.
A complete part number is represented by the digits below.
Breakdown voltages are expressed in Volts for devices <1000V and
kV for devices
1kV. For example, UBD-550 is a 550V UBD series
device, and UBT-10.0 is a 10kV UBT series device.
