Since these are only a few of the contributing parameters, application testing is strongly recommended and should be used to verify performance in the application circuit.1. Fuse selection DescriptionDuring normal load conditions, the fuse must carry the normal operating current of the circuit without nuisance openings. However, when an overcurrent occurs the fuse must interrupt the overcurrent and withstand the voltage across the fuse after internal arcing. To properly select a fuse the following items must be considered: Application voltage (AC or DC) Normal operating current Ambient temperature Overload conditions and opening times Maximum available fault current Pulse (or Surge current, Inrush current, Start-up current) characteristics Physical size and available board space Standards requirements or environmental protection requestApplication Voltage:The voltage rating of the fuse must be greater than (or equal to) the maximum open circuit voltage Normal operating current: An operating current of 75% or less than rated current of fuse is recommended for operation at 25 to avoid nuisance openings.Ambient temperature: All electrical characteristics of fuse are rated and validated at an ambient temperature of 25.Both higher and lower ambient temperatures will affect the fuses opening and current carrying characteristics. Please refer to the temperature derating curve for individual product series found in the specifications.Overload conditions and opening times: Specific attention must be given to first overload operating points. For fuses, the first overload point is usually between 200% to 300% of rated current.Maximum available fault current: The interrupting rating of fuse must meet or greater than the maximum fault current of the circuit. 1 Fuse Selection GuidePulse current characteristics: Transient Pulse current is used to describe wave shapes that result from any start up, Inrush, Surge, or transient currents in a circuit. Electrical pulses produce thermal cycling and possible mechanical fatigue that could affect the life of the fuse. Initial or start-up pulses are normal for some applications and require the characteristic of a slow blow fuse.The fuses capability to withstand a surge pulse without causing thermal stress to the fuse element, which may result in nuisance openings, can be determined once the circuits pulse I2t is calculated. The circuit designer needs to properly size the fuse so that the fuses melting I2t value is greater than or equal to the pulse I2t divide by a pulse factor Fp.In design the selected fuse should have a I2t value much greater than the I2t value of pulse. The I2t value of a pulse can be approximated from the following formulas for a typical wave Shape, refer to P1.Physical size and available board space: Please refer to the product dimensions presented in Sartfuse product datasheet for specific information (such as 0603/1206/6125).Standards requirements or environmental protection request: Please refer to the product datasheet or contact us, we will supply specially service to you. 2.

Final determination of rated value From calculation results of step2 through step4 ,determine the rate valueStep6. Operation check using actual device.
