Where to buy parts. BOLD parts are common, we buy them by the reel and keep them handy in a chest of drawers.

Contents

Resistors

  • Get a cheap resistor kit from eBay so you have all common values available
  • 390R, 1K, 2K, 10K, 100K are most common in our projects, we buy them by the reel

  • Rectangular passive components
    • 0402 (1005 metric) : 0.04" × 0.02" (1.0 mm × 0.5 mm) Typical power rating for resistors 1/16 watt
    • 0603 (1608 metric) : 0.063" × 0.031" (1.6 mm × 0.8 mm) Typical power rating for resistors 1/16 watt
    • 0805 (2012 metric) : 0.08" × 0.05" (2.0 mm × 1.25 mm) Typical power rating for resistors 1/10 watt
    • 1206 (3216 metric) : 0.126" × 0.063" (3.2 mm × 1.6 mm) Typical power rating for resistors 1/8 watt

Capacitors

These are common properties given with capacitors:

  • Value: pF, nF, uF, F, etc. Usually taken from a schematic, partlist, or datasheet.
  • Voltage: We choose something at least double the operating voltage. If it is a 0.1uF cap decoupling a 3.3volt power pin, we use a cap rated for at least 6.6volts.
  • Tolerance: How close to actual value. Not really important unless a audio or analog application. We don't ever worry about this for digital stuff.
  • ESR: For most digital hobby stuff this is never important, maybe switch mode power supplies. If it is, the design probably says what to do.
  • 100nF is the same ad 0.1uF. This common value is generally used on every power pin of a digital chip. Commonly called a decoupling capacitor
  • Get a cheap capacitor kit from eBay so you have all common values available
  • 18pF, 0.1uF, 1uF (ceramic), and 10uF (tantalum) are most common in our project, we buy them by the reel

Ceramic

  • Cheap, available from pF to 1uF ranges.
  • Commonly rated for 25-50volts.
  • Unpolarized, no +/- side.

    • 0603 (1608 metric) : 0.063" × 0.031" (1.6 mm × 0.8 mm)
    • 0805 (2012 metric) : 0.08" × 0.05" (2.0 mm × 1.25 mm)

Tantalum

  • Faster than aluminum, larger values than ceramic, and much more expensive. Tantalum is a conflict mineral we try to avoid.
  • Watch out, these are commonly rated for only 6-16volts.
  • We prefer the 1206 sized A case/Kemet A 10uF when we need these.
  • Polarized: there is a +/- side, + is usually marked by a line etched or printed on the package.

    • EIA 3528-21 (Kemet B, AVX B): 3.5 mm × 2.8 mm × 2.1 mm
    • EIA 6032-28 (Kemet C, AVX C): 6.0 mm × 3.2 mm × 2.8 mm

Aluminum

  • Larger values than ceramic, but much bigger package. Like a through-hole capacitor in an SMD holder.
  • Commonly rated for 10-35volts.
  • Polarized: there is a +/- side, - is usually marked by a line on through hole parts. On SMD packages the carrier usually has slanted edges (cut corners) on the + side.

Clock source

  • HC-49/US is always preferred. It is the cheapest ($0.40) and most standard
  • Smaller surface mount crystals start at $1+ each, and don't have standard packages

    • DPAK (TO-252): discrete packaging. Developed by Motorola to house higher powered devices. Comes in three- or five-terminal versions
    • D2PAK (TO-263) - bigger than the DPAK; basically a surface mount equivalent of the TO-220 through-hole package.

Ferrite Bead

  • We usually just make sure the bead is rated for enough current because we only use them for power filters
  • If a special impedance is required, the part datasheet or application example will specify
  • We just recently moved to 0603

Buttons switches

  • DTSM-6 (6mm) is the typical surface mount size
  • 5.2mm is a smaller SMD button that is more pick and place friendly. We see it used by Seeed, SparkFun, Adafruit, etc. This is our standard button too. Also called 4.8mm in some specs

Connectors

  • 0.1" (2.54mm) header is the standard width of bread boards
  • 2.1mm power jacks are the most common size. Center is +, outside is -
  • There is no standard for ethernet jacks with integrated magnetics, check your datasheet twice!
