Product Overview

The TMOV series Thermally Protected Radial Leaded Metal Oxide Varistor (MOV) represents a new development in integrated circuit protection. Comprised of radial leaded metal oxide varistor (MOV) 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. The TMOV® 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. The TMOV® varistor offers 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.
  • Designed to facilitate compliance to UL1449 for SPD products
  • High peak surge current rating up to 10kA
  • Wave solderable
  • Standard lead form and spacing option
  • -55 to 85°C Operating temperature range
  • Three-lead version available for indication purposes
