    Metal-OxideVaristors (MOVs)  
    Radial Lead Varistors > TMOV® and iTMOV® Varistor Series  
    ®
    ®
    RoHS  
    TMOV and iTMOV Varistor Series  
    Description  
    The LittelfuseTMOV® and iTMOV® thermally protected  
    varistors represent a new development in integrated  
    circuit protection. Both versions are comprised of radial  
    leaded Metal Oxide Varistors (MOVs) with an integrated  
    thermally activated element designed to open in the  
    event of overheating due to the abnormal overvoltage,  
    limited current, conditions outlined in UL1449. TheTMOV®  
    and iTMOV® varistor’s integrated thermal element, in  
    conjunction with appropriate enclosure design, helps  
    facilitate SPD module compliance to UL1449 for both cord  
    connected and permanently connected applications.  
    TheTMOV® and iTMOV® varistors offer quick thermal  
    response due to the close proximity of the integrated  
    thermal element to the MOV body. The integrated  
    configuration also offers lower inductance than most  
    discrete solutions resulting in improved clamping  
    performance to fast overvoltage transients.

    The iTMOV® varistor differs from theTMOV® varistor by the  
    inclusion of a third lead for the purpose of indicating that  
    the MOV has been disconnected from the circuit. This lead  
    facilitates connection to monitoring circuitry.

    IECQ-C BSI 15.0009  
    40021525  
    AdditionallyTMOV® and iTMOV® varistors are wave  
    solderable, thus simplifying end product assembly by  
    reducing the the expense and rework associated with hand  
    soldering operations.

    Note :TheTMOV® and iTMOV® varistors are intended, in conjunction  
    with appropriate enclosure design, to help facilitate SPD module  
    compliance to UL 1449, 3rd Edition Section 39.4 (abnormal  
    overvoltage limited current requirements). Under these extreme  
    abnormal overvoltage conditions, some units will exhibit substantial  
    heating, arcing and venting prior to opening. Modules should be  
    designed to contain this possibility. Application testing is strongly  
    recommended.  
    For applications exceeding 85°C ambient temperature, the peak  
    surge current and energy ratings must be reduced as shown  
    above.

    Wave Solder Profile  
    Because the TMOV® and iTMOV® varistors contain a thermal protection device, care must be taken when soldering the devices into place.  
    Two soldering methods are possible. Firstly, hand soldering: It is recommended to heat-sink the leads of the device. Secondly, wave solder-  
    ing: It is critically important that all preheat stage and the solder bath temperatures are rigidly controlled.

    iTMOV® Varistor Application Examples  
    The application examples below show how the indicator lead on the iTMOV® varistor can be used to indicate that the  
    thermal element has been opened. This signifies that the circuit is no longer protected from transients by the MOV.  
    Application Example 1  
    Application Example 3  
    In this case, the LED is normally on, and is off when the  
    thermal element opens.  
    This circuit illustrates the use of the monitoring lead of  
    the iTMOV® varistor to ensure that equipment is only  
    operated when overvoltage protection present. In normal  
    operation the load switch relay solenoid is powered via the  
    indicator lead of the iTMOV® varistor. In the event of the  
    thermal element being activated, the relay will de-activate,  
    cutting power to the protected circuit and the fault LED will  
    illuminate.
