    heya guys i have a question

    i have gotten my hands on 2x 290watt UPS and 4x 2700watt UPS racks that belong in a server rack,

    now i am in the proces in checking em and starting up,
    on a visual inspection of 1 of the big 2700 watt one i found that a big cap has bursted and leaked waxy stuff on the pcb witch i cleaned,
    the cap is an R.46 MKP X2 SH, 4,7uF 275Vac,
    i looked on Ebay and there is just 1 in the states for 20$ witch i find to much and he isnt shiping worldwide.
    now i could order a cap witch is roughly the same size but a bit shorter and only 2.2uF,

    wil this work???????

    this project isnt a race because i have 3 others to play whit but i do whant this one to work again

    thx alot in advance

    I found 3 on Mouser between $3 and $5.

    If you still want to use 2.2μF caps, use 2 in parallel to increase the capacitance to 4.4μF.
