CP Series Data Sheet [ /Title (CP Series) /Subject (Tubular MetalOxide Varistors) /Autho r () /Keywords (Littelfuse, Inc., Suppression Products, TVS, Transient Suppression, Protection, Highreliability, High Reliability, Mil, Hi-rel, July 1999 File Number 2188.5 Tubular Metal-Oxide Varistors Features 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 VM(AC)RMS. Their internal 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. • Unique Coaxial Design and Mounting Arrangement in Tubular Form 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. • Designed to be Integrated Within Standard Connector Assemblies • Wide Operating Voltage Range VM(AC)RMS . . . . 6V to 150V • Can be Used with 16, 20, or 22 Gauge Standard Connector Pins • No Derating up to 125oC Ambient Packaging CP SERIES The CP Series is supplied in Bulk Pack.

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. 100 PERCENT OF RATED VALUE V38CP20 90 80 70 60 50 40 30 20 10 0 -55 50 60 70 80 90 100 110 120 130 140 150 AMBIENT TEMPERATURE (oC) PERCENT OF PEAK VALUE FIGURE 1.
