| Datasheet | Download Datasheet |
The OptiFuse RASR-350 is a 3.5 A hold battery-strap resettable PTC fuse, rated 30 VDC maximum.
A PTC fuse carries its hold current indefinitely; on an overcurrent it heats, its resistance rises sharply and it limits the current to a trickle, then resets on its own once the fault is removed and power is cycled. This one always trips at 6.3 A, in max. 3.0 s at 5 x IH.
It withstands a fault current of up to 100 A at rated voltage. Resistance: minimum 0.017 Ω, maximum 0.031 Ω, 0.050 Ω maximum one hour after tripping. Tripped, it dissipates typically 2.5 W. It operates from -40 to +85 °C.
Construction: outline 31.8 x 13.5 x 1.1 mm (max.); nickel strap, 0.13 mm.
