Radial Lead Varistors > TMOV
®
25S Varistor Series
TMOV
®
25S Varistor Series
Description
RoHS
Metal Oxide Varistors (MOVs) are rated for specific AC line
operating voltages, and exceeding these limits through the
application of a sustained abnormal over-voltage condition
could result in overheating and damage to the MOV.
The Littelfuse TMOV
®
25S Varistor Series was designed to
address this condition in a single integrated package.
The TMOV
®
25S Varistor Series incorporates a patented
integrated thermally responsive element within the body
of the device which will open-circuit the varistor in case of
overheating due to the abnormal over-voltage events.

The TMOV
®
25S Varistor Series meets the surge suppressor
component recognition requirements of UL1449 3rd
edition for both cord connected and permanently
connected SPD end products.

Wave Solder Profile
Because the TMOV
®
25S Varistor Series contains a
thermally responsive device, care must be taken when
soldering the device into place. Two soldering methods
are possible. Firstly, hand soldering: We recommend
the use of pliers to heat-sink the leads of the device.
Secondly, wave-soldering: This is a strenuous process
requiring pre-heat stages to reduce the stresses on
devices.
It is critically important that all preheat stage and the
solder bath temperatures are rigidly controlled. The
recommended solder for the TMOV
®
Varistor Series
is a 62/36/2 (Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37 (Sn/
Pb). Littelfuse also recommends an RMA solder flux.
SAC solders (SnAgCu) are recommended for Lead-free
applications.
