Tubular Metal-Oxide Varistors
The CP Series of transient voltage surge suppressors are
metal-oxide varistors (MOVs) of tubular construction. These
varistors are intended for mounting within a multipin
connector assembly. This series is available in a wide range
of voltage ratings from 6V to 150V V
dimensions allow them to be used with 16, 20, or 22 gauge
connector pins. The unique coaxial mounting arrangement of
these tubular varistors allow them to become part of a
transmission line itself. Added inductive lead effects are
eliminated.
Varistor action takes place between the inside and outside
diameters of the tube. Typically, data or signal lines make
electrical connection to the inside of the tube. The outside
tube surface is then connected to ground or common.
The CP Series is supplied in Bulk Pack.

Power Dissipation Ratings
Should transients occur in rapid succession, the average
power dissipation required is simply the energy (wattseconds) per pulse times the number of pulses per second.
The power so developed must be within the specifications
shown on the Device Ratings and Specifications table for the
specific device. Furthermore, the operating values need to
be derated at high temperatures as shown in Figure 1.
Because varistors can only dissipate a relatively small
amount of average power they are, therefore, not suitable for
repetitive applications that involve substantial amounts of
average power dissipation.
