FireWire 1814 broken inductor
I have a FireWire 1814 and the Inductor I7 broked i don't why, anyway. The ferrite core got broke.
The value is 470uH. Height 15mm Diammeter 15mm But i need to know the impedance to buy a new one. 210 Ohms 377 Ohms etc Anyone knows this value. Yes the value was 470uH i wrote it wrong Thank you Last edited by vr_fox; 08-20-2016 at 10:39 AM. Reason: wrong value |

What is this doing? A power supply filter choke? It's not impedance that is usually quoted (or you'd need to spec a frequency). It's DC resistance, so if you are worried about it measure the coil of the one you have with a multimeter. What will matter is getting one that fits with the same mount type however this one is mounted. Look though DigiKey and Mouser for what you need. |

Re: FireWire 1814 broken inductor
This are the Inductors 470uH in mouser.
http://www.mouser.mx/Passive-Compone...yzvqm3Z1z0x280 I did measure the coil but its broken and measure 8 Ohms. You can see the photos. |

Re: FireWire 1814 broken inductor
This is the Mouser list of inductor 470 uH 14 -16 mm (same size as original)
http://www.mouser.mx/Passive-Compone...yzvqm3Z1z0x280 You can see in the photos that the core is broken. I mesure the impedance and its 8 Ohms, but don't know if the value is wrong because is broken. It also measures 364 uH. |
