Comment on Who created MELFS and who hurt them?

  If you see that designer, you should ask them. There must be a reason they use them other than being a misanthrope.

  I spent 3 hours fighting with a Fuzion tonight and even with the special MELF heads it drops enough to reliably jam up other component feeders. Unfortunately our customers pick what exact parts we use so we can’t just change them out for something equivalent but less hateful and I don’t communicate with them so I can’t ask why.

  I’m starting to think MELFs are just pushed by big component to get people to buy more components (because the machines throw half of them on the ground.)

    You guys made me curious, so I checked Wikipedia:

    Despite their handling difficulties, and in the particular case of MELF resistors, they are still widely used in high-reliability and precision applications where their predictable characteristics (e.g., low failure rate with well-defined failure modes) as well as their higher performance in terms of accuracy, long-term stability, moisture resistance, high-temperature operation far outweigh their disadvantages.

      I saw that earlier and at first I was thinking that must be BS because none of our class 3 products use them. But, thinking about it now, almost all of our class 3 products are medical products. Meaning they are only ever going to be used in relatively clean and climate controlled environments.

      The products we run that most frequently use MELFs are the class 2 products that are going to be used in more rugged environments (like ag products). So if they are more rugged environmentally speaking then that does make sense. It won’t stop me from complaining about them though.

        I have never seen them in my short time working on space electronics.

    Sorry for the slow response. I’ve seen the conversation has continued so this matters less now… But. Our guy that used them retired a few months back. And to your point, he was a misanthrope
