Five wire XY suppressor
The 5 wire XY capacitor just blew up in my Unimat lathe It is:
ERO F1740-325-5522 1x0.025ufX 2x 2500pfY 4A I cannot find anything with this part no. Size is critical since it is fitted in the motor housing. Any ideas? Thanks Trevor |

Re: Looking for 5 wire XY suppressor
Looks like Vishay F1740-322-5511 is the thing, but I can't find one of them either!

Nearly the same values, only three leads though. |

Re: Looking for 5 wire XY suppressor
Its for suppression so the actual component could be placed elsewhere.
5 wire will have an x and two y caps and a series choke pair in each lead. 3 wire will likely not have a choke. |

Re: Looking for 5 wire XY suppressor
Ok, can't find the correct size and the Ebay item is expensive, so I have built an external filter using X & Y capacitors acquired from old PC power supplies, mounted in a small plastic box close to the lathe.
Trevor Mods this can be closed unless you think it may be useful for others, thanks |

Re: Five wire XY suppressor
5 wire ones almost always have no additional choke inside, so you should be good with any 3 or 5 wire one (or with separate capacitors of course).
The reason that the exact original type or a direct replacement isn't available is probably that the manufacturer discontinued paper capacitors. I would be VERY weary of using new old stock, as stocking is often worse for their remaining life than regular usage. When replacing, polypropylene dielectric is preferred. |
