iTMOV Series - Thermally Protected Varistor Series with Indicating Lead

TMOV_iTMOV1
TMOV and iTMOV Varistor Series
 
The Littelfuse TMOV and iTMOV thermally protected varistors represent a new development in integrated circuit protection. Both versions are comprised of radial leaded MOVs (Metal Oxide Varistors) with an integrated thermally activated element designed to open in the event of overheating due to the abnormal overvoltage, limited current, conditions outlined in UL 1449.
 
The iTMOV varistor differs from the TMOV varistor by the inclusion of a third party lead for the purpose of indicating that the MOV has been disconnected from the circuit. This lead facilitates connection to monitoring circuitry.
 

Features:

  • RoHS compliant and Lead–free available
  • Patented integrated thermal protection device - Patent #US6636403
  • Designed to facilitate compliance to UL1449 3nd Edition for SPD product
  • High peak surge current rating up to 10kA
  • Wave solderable
  • Standard lead form and spacing option
  • Low leakage
  • -55°C to +85°C operating temp range
  • Three-lead version available for indication purposes
