| Datasheet | Download Datasheet |
The OptiFuse RS120-130 is a 1.3 A hold radial-lead resettable PTC fuse, rated 120 VAC/DC 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.
It withstands a fault current of up to 10 A at rated voltage and interrupts up to 135 V. Resistance: minimum 0.12 Ω, 0.30 Ω maximum one hour after tripping. Tripped, it dissipates typically 2.64 W. It operates from -40 to +85 °C.
Construction: outline 15.5 W x 20.6 H x 4.1 T mm (max.); lead spacing 5.1 mm; leads 20 AWG (0.81 mm); tin plated copper.
