POLYSWITCH® Battery Protector
Surface Mount > ITV4030 Series
ITV4030 12A Series
Description
ITV4030 Series is a three terminals surface mountable
battery protector which is designed to against both
overcurrent and overvoltage (overcharging). A fuse element
is embedded to cut off the circuit when overcurrent issue
happens. A heater is also directly embedded under the
fuse element, it will generate heat to blow the fuse once
overvoltage detected by IC or FET.

Installation and Handling Guidelines
• Before and after mounted, the ultrasonic-cleaning or
immersion-cleaning must not be done to ITV device. The
flux on element would flow, and it would not be satisfied
its specification when cleaning is done. In addition, a
similar influence happens when the product comes in
contact with cleaning solution. These products after
cleaning will not be guaranteed.
• Silicone-based oils, oils, solvents, gels, electrolytes,
fuels, acids, and similar will adversely affect the
properties of ITV devices, and shall not be used or
applied.
• Please DO NOT reuse the ITV device removed by the
soldering process.
• ITV devices are secondary protection devices and are
used solely for sporadic, accidental overcurrent or
overtemperature error condition, and shall NOT be used if
or when constant or repeated fault conditions (such fault
conditions may be caused by, among others, incorrect
pin-connection of a connector) or over-extensive trip
events may occur.
• Operation over the maximum rating or other forms of
improper use may cause failure, arcing, flame and/or
other damage to the ITV devices.
• The performance of ITV devices will be adversely
affected if they are improperly used under electronic,
thermal and/or mechanical procedures and/or conditions
non-conformant to those recommended by manufacturer.
• Customers shall be responsible for determining whether
it is necessary to have back-up, failsafe and/or fool-proof
protection to avoid or minimize damage that may result
from extra-ordinary, irregular function or failure of ITV
devices.
• There should be minimum of 0.1mm spacing between
ITV and surrounding compounds, to maintain the product
characteristics and avoid damage other surrounding
compounds.
• This product is designed and manufactured only
for general-use of electronics devices. We do not
recommend that it is used for the applications military,
medical and so on which may cause direct damages on
life, bodies or properties.
