Electrical Characteristics

SF-0603F Series - Fast Acting Surface Mount Fuses

* RoHS Directive 2002/95/EC Jan 27 2003 including Annex.

** Bourns is using the definition that appears to be the prevalent definition used as the industry standard at this time. The Bourns definition of “halogen-free” is:

Bromine (Br) content:

≤ 900 ppm; Chlorine (Cl) content: ≤ 900 ppm; Total Br + Cl content: ≤1500 ppm.

Specifications are subject to change without notice.

Customers should verify actual device performance in their specific applications.

***Resistance value was measured with less than 10 % of rated current.

Reliability Testing

Parameter

Requirement

Test Method

Carrying Capacity..................................... No fusing....................................................Rated current, 4 hours

Fusing Time .............................................. Within 1 minute ..........................................200 % of its rated current

Interrupting Ability .................................... No mechanical damages ...........................After the fuse is interrupted, rated voltage applied for

30 seconds again
