0ZCM0003FF2G – 30mA 30V PTC Resettable Fuse – 0603 Package

A Bel PTC consists of a block of polymeric material containing conductive carbon granules which is sandwiched between two conductive metal plates. When this polymer block reaches approximately 125C, either due to current passing through it via conductive chains of carbon particles or due to an external heat source; it swells volumetrically. This expansion breaks apart a majority of the chains of carbon granules that run randomly between the two conductive plates. This behavior results in a sharp increase in resistance
across the two plates which all but eliminates current flow through the device, allowing just enough residual current flow to maintain the block’s internal temperature at 125C.
This product is known as Polymeric PTC Resettable Fuse, 30mA Fuse, 30mA Resettable Fuse, Resettable Fuse, SMD Resettable Fuse, SMD Fuse.
