Breakdown Voltage

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.
