The Cooper Bussmann family of PolyTron polymer positive temperature coefficient (PPTC) resettable overcurrent protective devices provide low resistance and fast trip times. These devices protect applications that are sensitive to high ambient operating temperatures or subject to frequent overcurrent conditions, such as consumer electronics, I/O ports, medical equipment, and process-control applications. The products are available in SMD and radial leaded packages. SMD devices are rated 6 to 60 Vdc with the 1206 package covering 0.05 to 2.0 amps, and the 1812 size covering 0.1 to 3.0 amps. The radial leaded devices are rated for 16 Vdc, 30 Vdc, and 60 Vdc.
