Resettable Fuses: The Backbone of Your Electronic Devices
Introduction to Resettable Fuses Resettable fuses, also known as polymeric positive temperature coefficient (PPTC) devices or polymer resettable fuses, are electronic components used to protect circuits from overcurrent conditions. They are designed to limit the amount of current that flows through a circuit by increasing their resistance in response to excessive current levels. How Resettable…
