    Default Types of resistors and capacitors

    I'm making an Access database to "finally" keep an inventory of the gazillion parts I have lying around and to label drawers and cabinets. I'm tired of rumaging through bags and boxes.

    I've searched google, wikipedia and various sites, as well as checked Digikey to see what they use. So far I have:

    Resistors:
    Carbon composition (old baked type)
    Carbon film (common today)
    Ceramic
    Metal element (?)
    Metal film
    Metal foil
    Metal oxide film
    Wirewound
    Thick film
    Thin film

    Capacitors:
    Aluminium electrolytic
    Aluminium polymer
    Ceramic
    MICA
    PTFE
    Niobium Oxide
    Tantalum
    Tantalum polymer
    Silicon
    Thin film
    Acrylic metalized
    Polyester
    Polyester metalized
    PEN
    PET
    PP
    PP metalized
    Polymer metalized (same as aluminium polymer ?)


    The problem is that not all sites use the same words. I could use a hand in removing duplicates and adding any missing varieties.

    I ignored the mega-capacitors used in high tension applications. It's not like I'm going to build a dam.

    at a storage drawer per possible value? Or just a drawer per value you HAVE? Could be an AWFUL lot of drawers!!!!

    Yup, 5 cabinets of 60 drawers. Planning on adding 5 more cabinets at least. So lets say about 600 drawers, probably more knowing me.

    Wait 'till I post pics of the mancave once it's finished.

    Don't forget a drawer for a bazillion different physical sizes of surface mount stuff.

    I usually use NTE for parts and looking at their site http://www.nteinc.com/capacitors.php?a=2 they have several different names from you've got. I think you'd have to know the manufacturer's part number to find the exact name as I'm sure some are proprietary.

    I ended up using something like this http://www.grainger.com/product/DURH...Code=P2IDP2PCPas I think you can cram more parts in a smaller area. Of course if you've got massive quantities this won't work.

    Just a few thoughts. Hope they help.

    I started with these:




    Then added these for bulk:




    Recently got 3 more blue cabinets (yes I can't count, that's 6 not 5) and 3 white ones for bulk:




    But I plan on getting several more blue ones. I tend to get a lot of variety for testing and now only buy specific items in bulk. So yeah, that's gonna be a lot of data to enter, lots of labels to tape up.

    I did get a new barcode app for my phone that works beautifully and doesn't access personal info. Now I have to research bluetooth technology to get the scanned code to Access 2002 on my laptop.

    Got myself a BT dongle for a few bucks:

    Not sure how it can be used so far.

    I have 10 of those 60-drawer cabinets, Resistors, capacitors, LEDs, analogue ICs, Digital ICs, Transistors (inc FETs etc), inductors, hardware etc etc etc. Plus three larger cabinets for other stuff.

    Even with the cabinets I have now I can only allocate ONE set of drawers to resistors (E12 series only!!!) as there are 84 values there alone so I'm already doubling-up! I don't separate resistors by 'type' any more - they all go into the value drawer applicable.
