SMD1206 Series PPTC Resettable Fuse | Surface-Mount Overcurrent Protection for Power & Interface Applications
The SMD1206 Series is a PPTC (Polymeric Positive Temperature Coefficient) resettable fuse in a 1206 (3216 metric) package, offering higher hold current ratings (up to 2A) and typical voltage ratings from 6V to 60V. During fault conditions, the device transitions to a high-resistance state to limit current, and automatically resets when normal conditions resume. This series is ideal for battery packs, DC power outputs, USB and HDMI ports, industrial control circuits, and consumer electronics. Fully compliant with RoHS, REACH, and UL94V-0 standards, and suitable for SMT assembly and reflow soldering.
