Description

The Littelfuse TMOV

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 UL1449. The TMOV

and iTMOV

conjunction with appropriate enclosure design, helps

facilitate TVSS module compliance to UL1449 for both cord

connected and permanently connected applications.

The TMOV

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

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

solderable, thus simplifying end product assembly by

reducing the the expense and rework associated with hand

soldering operations.
