125V Slow Blow Surface Mounted Fuse

6125 2410 125V Slow Blow Pulse Tolerant Chip Multilayer Surface Mount Fuse 15A

Description of 125V Slow Blow Surface Mounted Fuse

The 2410(6125) 125V Slow Blow Surface Mount Fuse is a Wire-In-Air SMD Fuse which is very suitable for secondary level over current protection applications.
Pulse Tolerant chip fuses has high inrush current withstand capability and provide overcurrent protection on DC power systems. Silver fusing element, monolithic and multilayer design provides strong arc suppression characteristics. These RoHS-compliant surface-mount devices facilitate the development of more reliable, high performance consumer electronics such as laptops, multimedia devices, cell phones, and other portable electronics.

Selection of 125V Slow Blow Surface Mounted Fuse

Fuse selection seems straightforward, in that, you pick one which has a current rating just a bit higher than your worstcase system operating current. Unfortunately, it’s not that simple. There are derating considerations for operating current and application temperature. Turn-on and other system operations (like processor speed changes or motor start up) cause current surges or spikes that also require consideration when selecting a fuse. So selecting the right fuse for your application is not as simple as knowing the nominal current drawn by the system.

Why should the DCR of a fuse be measured at a load of no more than 10% and an ambient temperature of 25°C ?

The internal resistance of a fuse is an index reflecting its consumed power in the circuit. The higher the resistance, the more power consumed. For fuses, two parameters can be used to check this index: voltage drop or cold resistance.

Voltage drop: the voltage drop reading after the fusing element reaches thermal balance under rated current. To measure it, apply rated current to the fuse and wait until the reading is stable. It may take a few minutes. It is a little inconvenient and time-consuming.

Cold resistance: the reading of cold resistance basically under no load condition, easy and fast.

Therefore, the cold resistance method is always preferred for fuse check. The load of less than or equal to 10% means basically no load or heating condition, so there will be no thermal balance process, while the ambient temperature itself has a certain effect on fuse performance. All performance indexes of a fuse are parameters in ordinary atmospheric condition, i.e. 25°C. The cold resistance of a fuse, if not measured under the above-mentioned conditions, may not be accurate.
