OUR EXPERTISE
Littelfuse PolySwitch Circuit Protection began almost 40 years ago, pioneering the field
of resettable PPTC (polymeric positive temperature coefficient) technology with our
PolySwitch product line. Today our extensive product portfolio reflects our expertise
in developing different material platforms that help designers create safe and reliable
applications.
BATTERY PROTECTION PRODUCTS
Our devices for battery protection include hybrid MHP-TA devices, PolySwitch PPTC
strap and disc devices, low rho SMD devices and surface-mount fuses. By drawing upon
our long history in materials science and customer knowledge, our products respond
to evolving battery technologies to meet specific design requirements. As a result, our
battery protection products offer engineers enhanced design flexibility and the ability
meet regulatory requirements – all while helping them achieve energy-saving, space- and
cost-effective designs.
In choosing the appropriate battery circuit protection device, designers should consider
the requirements of the end use application, cell chemistry and cell geometry, in addition
to the relevant electrical specifications of each application.
