Polymer fuses

Polymer fuses or resettable fuses - are components that protect your circuit against overloads. It is an ingenious invention - due to the polymer characteristic their resistance increases with the temperature corresponding to the current flowing through a circuit. So, in principle, polymer fuses work in a very similar way to thermistors. To learn more about the differences see our forum and tutorial section. The parameters that specify fuse performance are the operating current and operating voltage. Again, knowing the requirements for these parameters is crucial to avoid damaging your circuit. In our offer we have fuses from 60 to 90V voltage and from 100mA to 900mA current.
