The 250R120-RCZR is a polymeric PTC resettable fuse from Littelfuse, part of the 250R Series designed for telecom applications. It features a hold current of 120 mA and a trip current of 240 mA, with a maximum voltage rating of 250 V AC and an operating voltage of 60 V DC. The device can interrupt fault currents up to 3 A and has a typical power dissipation of 1 W in the tripped state.
The fuse offers fast time-to-trip, tripping within 3 seconds at 1.0 A in 20°C still air. Initial resistance ranges from 4 Ω (minimum) to 16 Ω (maximum), with a typical value of 8 Ω. It is housed in a radial disc package with through-hole mounting, lead spacing of 5.10 mm, and dimensions of 6.50 mm x 4.60 mm x 11.00 mm.
This component is RoHS compliant, lead-free, and halogen-free, making it suitable for environmentally conscious designs. It operates over a temperature range of -40°C to +85°C.
