4、t to change without notice.2 HOW DOES THE RESETTABLE FUSE WORK FUZETEC resettable fuses are designed and made of patented novel polymeric PTC material in thin chip form,developed solely by FUZETEC.With electrodes and leads attached on both sides,it is placed in series to protect a circuit.At“normal

5、operating condition”the device remains at an extremely low resistance(milli-ohms)and allows the electrical current to flow through it without any restriction.When overcurrent conditions occur,the polymeric PTC material heats up and its resistance increases sharply.Such a sharp resistance increase(to

6、 an insulated status)cuts off the current in the circuit,and consequently protects the element and device in the circuit.Upon fault current being removed,the resettable fuse cools and its resistance drops to the original extremely low value.The resettable fuse is“reset”and allows the current through

7、 the circuit again.TRIP CURRENT,HOLD CURRENT AND THERMAL DERATING Trip Current(IT)and Hold Current(IH)of FUZETEC resettable fuse are rated at 23.Typically its Trip Current is twice as much as its Hold Current.FUZETEC device does not trip at or below its rated Hold Current,and will trip at or above i

8、ts Trip Current value.However,due to PTC effect both IT and IH reduce with ambient temperature increase and vice versa.As shown bellow,the currents are reduced nearly 50%at 85 and increased to 150%at-40.II-FUNDAMENTAL Hold&Trip Current and Thermal Derating Curve050100150200250300-40-20020406080Ambie
