Description
The Littelfuse TMOV
®
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. The TMOV
®
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.
The TMOV
®
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 the TMOV
®
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.
Additionally TMOV
®
and iTMOV
®
varistors are wave
solderable, thus simplifying end product assembly by
reducing the the expense and rework associated with hand
soldering operations.
