| Datasheet | Download Datasheet |
The OptiFuse R0603-003-R is a 30 mA hold 0603 surface-mount 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 90 mA, in max. 1.00 s at 0.20 A.
It withstands a fault current of up to 40 A at rated voltage. Resistance: minimum 6.00 Ω, 50.00 Ω maximum one hour after tripping. Tripped, it dissipates typically 0.5 W. It operates from -40 to +85 °C.
Construction: outline 1.80 x 1.00 x 0.75 mm (max.); pure tin terminations.
