1) The will trip only at 1A. In other words, the trip current is twice as high as the hold current. Isn't that a bit dangerous for the PC?
2) The has a R_min of . That looks okay. However, the is . The datasheet says: R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow soldering of 260°C for 20 sec. Could this be a problem?
