This part, the TRF250-145-2 from Littelfuse, is a polymeric PTC (Positive Temperature Coefficient) resettable fuse designed for overcurrent protection. It automatically resets after the fault is cleared, making it suitable for applications where replacing a fuse is impractical.
Key electrical specifications include a hold current of 145 mA, a maximum voltage rating of 60V DC, and a typical time to trip of 5 seconds. The initial series resistance is 14 Ω, and the device operates over a temperature range of -40°C to 85°C.
Mechanically, the fuse is a through-hole component with a radial disc package measuring 6.50mm x 4.60mm x 11.00mm, featuring a lead spacing of 5.08mm. It is RoHS and REACH compliant (unverified).
