Pinkish resistor with red, red, gold, gold, white (or vice versa - doesn't make sense either way). Any thoughts? Sent from my ONEPLUS A3000 using Tapatalk |

I ddon't know a lot, but my best first guess would be some kind of old axial lead capacitor. Paper wound. But the board says R10. Makes no sense. If you have a ESR meter you may want to try it and then see what the DC resistance (and continuity) of the part to help find out. What is this in? |

I think the pink denotes a fusible resistor. (As in, not all fusible resistors are pink, but if a resistor is pink, there's a decent chance it's fusible.) |

The first four bands are the usual IEC: red red gold gold = 2 2 x0.1 ±5% gives 2R2 ±5%. The fifth band is open season, unfortunately (resistor) manufacturer specific. These have a safety function because they burn up when something else fails short circuit. It would be a flame-proof fusible resistor. But I am not sure who made it, i.e. Yageo, KOA, Welwyn, TT, Futaba etc. Fifth band: White: fusible Gold: miniature fusible (usually with pink body) Yellow: "constant voltage fusibility" Black: sometimes wirewound fusible resistor, but I see film types too Violet: Vishay NFR25H Some series use coloured fifth band to denote fusibility overload rating (4x,8x,64x). |

Or use the brute force method - unsolder one end and get to it with a DMM ... :popcorn: |
