Steady-State Current Fuse Selection Method 1-1. Derating Coefficient for Steady-State Current: 0.7 Fuse use is predicated on usage at currents of 70% or less of their rated current. 1-2. Temperature Derating Coefficient: Multiply the derating for steady-state current by the effect of the ambient temperature. Ambient temperature -20 20 40 60 LM 1.05 1 0.96 0.92 LM DM HM 1-3. Derating for multiple fuse use: When mounting multiple fuses, heat generation must be taken into account. Please consult with us in advance. The following formula is used to determine the required rated current value for the fuse. Circuit Steady-State Current Value Rated Current Value Derating Coefficient for 1 Steady-State Current x Required Derating Sum * *1 This is calculated by multiplying all necessary deratings together. 2. Rush Current Fuse Selection Method Use the waveform closest to the actual measured waveform, and determine the joule integral value for rush current (refer to P7). In order to select a fuse for the determined rush current, assuming a fuse rush current durability of 100,000 times, ensure that the selected fuse fits the relationship below. I2t of fuse breakage > I2t of rush current / resistance to rush current *2 *2 Resistance to rush current: 0.3 Please perform evaluation and confirmation of the selected fuse within actual equipment, including fuse operation under abnormal current application, before use. Fuse selection If the fuse selection process is unclear, please contact us with as much of the information below as can be provided, so that we may assist you in selection. Materials: Operating voltage of circuit, operating current of circuit, presence or absence of multiply mounted fuses, rush current application waveform, abnormal current, etc. Insulating material(s)Phenol resin (Transparent products are PES resin), FR-PBT resin Soldering conditions260 max. 5s Cleaning solventsEthyl alcohol, isopropyl alcohol Notes) Ultrasonic cleaning is not covered by warranty.
