    Scholastic Electronics Lab with Fiber Optics

    I have a Scholastic Electronics Lab with Fiber Optics kit that I purchased a while ago. The capacitors included in the kit didn't go bad, but were of unheard of generic brands.


    Two "yongda" 47uf 16V capacitors along with one "Chang" 0.47uf 50V capacitor.

    Pictures of the kit:



    I have "recapped" this kit with:
    Receiver:
    1 "yongda" 47uf 16V capacitor -> 1 Panasonic FC series 47uf 50V capacitor
    1 "Chang" 0.47uf 50V capacitor -> 1 Panasonic FC series 2.2uf 50V capacitor

    Transmitter:
    1 "yongda" 47uf 16V capacitor -> 1 Panasonic FC series 47uf 50V capacitor




    The kit works fine with the new capacitors I installed.

    I know this kit is intended for children, but it's a shame that Scholastic included cheap capacitors with it. Are those cheap capacitors even lead-free/RoHS compliant?

    look, its meant to be cheap so kids have to beg ma and pa for a new one each time the catalog come in. look at the card board bases. see what i mean? no concern for quality?

    btw, why did you buy it in the first place?

      Well it's not like the capacitors will be over-stressed in that kit, hence why the manufacturer didn't bother to put higher-end caps. If general purpose caps work, then that's what the manufacturer will use. I bet that even with these cheap chinese caps, the kit will last pretty long.

        I'd understand that cheap capacitors would be good enough for this kit, high quality low ESR capacitors are overkill for it but I "recapped" it for fun and to see if they will also work well in the kit.

          Elite Capacitors? (450v 47uf power board Toshiba Vestel TV)
          by slybunda
          anyone heard of these caps before? at first glance i mistook them to be Elna caps but closer look and it was elite. not sure if they are known failure prone brand.
          also they are 47uf and 450v. why are they so large in height? i can get replacement 450v 47uf caps that are a quarter the height. what am i missing here?

          if i were to replace them what should i be looking for?

          they are on the power board of a toshiba (vestel) tv power board.

          by Alfieh
          hey Im very new to repairing electronics with capacitors as well as using a multimeter so I need so help/guidance fixing this issue

          Switching to AT&T fiber
          by Hondaman
          I hope you can help me. I might be smart in some ways, but I don't know much about networks.

          Right now, I have Spectrum/Time Warner for internet only (no cable TV). Their cable connects to the ARRIS CM550A. It provides one ethernet port (no wi-fi), which I plug in to the Linksys WRT-AC1200 (gives wi-fi). I placed an SSD inside a USB enclosure and plugged it into the back of the Linksys for network storage. After years of struggle, starting with the EIDE Travan-4 tape drive (expensive for what I got IMHO), I finally found a great solution for backup and file access!

          But...

          Looking to buy a microscope
          by Dannyx
          Good day and a belated happy New Year folks !
          Wow....feels like forever since I've had a chat with all the wonderful folks we got here - guess you could say I grew up and can look after myself now
          In all seriousness, I'm in need of some assistance choosing a microscope. I decided it's time I finally got one and I might as well put some of the money I earned caroling this year to good use

          The reason I'm turning to our community for advice is because I'd like to hear some thoughts from people who actually own a microscope already or at least worked with them hands-on,...
