AAC’s Digital Datasheet video series introduces the specs and applications of components—both new and familiar—straight from their datasheets.
Bourns IsoMOV Protectors
Bourns’ IsoMOV™ hybrid surge protective devices combine the features of the breakthrough surge performance EdgMOV™ Metal Oxide Varistor technology with an integrated Gas Discharge Tube (GDT) isolation structure.
Using proprietary computer-aided design techniques to model performance, Bourns engineers created the equivalent function of a discrete MOV and GDT in series.
Combining the functions of these two devices into a single package allows the GDT to block leakage currents through the MOV that may lead to premature failure while making the MOV more robust.
By integrating an MOV with a GDT, the hybrid device is tolerant of AC line voltage swells, and also offers low capacitance for low insertion loss, which is a clear advantage in power line communication applications. Additionally, the low capacitance ensures the IsoMOV will not impede AC or DC power line high-speed data rates. Boosting its design flexibility for engineers, IsoMOV protector surge ratings are comparable to the next larger size of a conventional MOV device. This gives designers the ability to select an IsoMOV protector that is smaller than the MOV option or upgrade to an IsoMOV protector of the same size to enhance the surge capability of their protection scheme.
After assembly of the core, leads are attached, and the unit is epoxy coated. The result is a familiar radial disc MOV package that is only slightly thicker and of substantially smaller diameter than similarly rated conventional devices.
