The N Series MF-SD013/250-2 is a resettable fuse manufactured by Bourns. It is a Polymer Positive Temperature Coefficient (PPTC) chip fuse with a current rating of 0.13A and a voltage rating of 60V. This particular part is also designed with 2O impedance rating. It has a small SMP size of 0.25 x 0.06 inch (6.4 x 1.5 mm) and it is surface mountable. The function of this component is to limit the current and protect electronic devices from over-current events or short-circuit conditions. It provides reliable over-current protection with low power dissipation and resistance. The PPTC family of parts provide fast, reliable, and repeatable overcurrent protection and are ideal for applications such as automotive systems, consumer electronics, computer circuits, and other high-power systems.
