Murata Electronics · Resettable Fuses · 0805
PRG21BC6R8MM1RA from Murata Electronics, in a 0805. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | One Sn-plated terminal electrode on the BaTiO3 semiconductive ceramic PTC body, rated for this 6.8 ohm MPN at a maximum voltage of DC30V and a maximum current of 5.5A. |
| 2 | 2 | passive | The opposite Sn-plated terminal electrode on the BaTiO3 semiconductive ceramic PTC body, which is non-polar and is used as the second connection of the posistor; the datasheet states the same 30V/5.5A limits for the part. |
