          Main technical parameters of self recovery fuse
          Publish:Shenzhen Tergy Technology Co., Ltd.  Time:2016-11-02
          From the self main technical parameters of the so-called electronic fuses, every engineer should pay more attention to the level, there may be a white engineer asked: the main parameters of self recovery fuse? Why do you say that? From the selection of self recovery, you do not know the parameters of the self recovery fuse you will type selection? Right! Today, this is the main technical parameters of the electronic dance to explain the self recovery fuse, look for the majority of my friends to a deeper understanding of the self recovery fuse.
          Self recovery fuse profile
          (Self recovery fuse profile)
          The main technical parameters of the self recovery fuse are the following:
          Self recovery fuse maximum voltage: refers to the 20 C: at both ends of the component can withstand the maximum voltage drop, generally 60V.
          Self recovery fuse to maintain current: refers to the minimum current of 20. For different types of components, the current value is not the same, generally ranging from tens of Ma to dozens of security.
          Self recovery fuse disconnect current: refers to the minimum current value of the component to turn off the device at 20 degrees C, also known as the trigger current. The current value is typically two times the current.
          The self recovery fuse triggered the maximum time off: under the condition of 20 DEG C, with 5 times the maximum time to maintain the current trigger element to disconnect the. The time is generally less than 205.
          The self recovery fuse disconnect power: power consumption components open at 20 DEG C off, generally a few hundred milliwatts to a few watts.
          The self recovery fuse original resistance at 20 DEG C before disconnecting the impedance element, usually a few milliohm to europe.
          The self recovery fuse after breaking resistance: the highest impedance off at 20 C for 1H elements, generally only a few dozen to a few European milliohm.
          The self recovery fuse element recovery time: in time from the shutdown to the closed conduction to remove 20 DEG C after the power is generally less than 20s.
