Description: If you ever find yourself connecting handfuls of resistors to the ground bus of your breadboard, you may consider these SIL-packaged resistors as a time-saving alternative. This Singe In-Line component is actually 5 individual 330 Ohm resistors that share a common terminal on pin 6 (denoted with a black dot).

These work great as current limiting resistors for rows of LEDs and two of these can replace 10 individual wire-lead resistors when hooking up our 10 LED bargraph displays. They also work well as pull-down resistors for DIP switches.

Note: These may come in yellow or black. They are the same product, just a different color, each equally pleasant.

  • OW! Stupid Singe In-line!

  • This might sound a bit silly, but does a resistor work the same way if you have it hooked up to ground? I’ve always done +V -Resistor-LED- V- not V+ -LED-Resistor- V-

    • Yes, it does. A current flow is reduced along the whole path when it has a resistance at any point.

      So, you can easily stick a resistor after an LED for the same result as it would have before said LED.

  • MUCH LOVE! I’ve been trying to steal these from various boards, but at $0.50, I’ll spend my time doing better things.
    Note: Resistance is +-2%

    • You’re very welcome! I found myself trying to desolder these from a board for a project and thought “if I’m doing these and working for SparkFun, I’m sure other people are doing the same…” and I was right.

    • +/- 2%? And all this time I thought resistance was useless and/or futile!

  • Please get these back in stock! They would go perfectly with your bar graph displays. That would make it so much easier to hook them up.

  • Since these only have 5 resistors each, you need two of them for each 10-LED bargraph you want to use. I found these resistor networks which have 10 resistors instead of 5. Tried them out today and they work perfectly.

  • I’m still learning here, so please help me out when it comes to understanding this. I get that it has one pin that is a common terminal pin, but when it comes to wiring it up, do I just put one lead on either side of the pins or is there another way that I am supposed to do it. Please help me here.

  • Without sounds stupid…im a bit confused at how these work? like for example you had 6 leds (that each needed a 330ohm resistor for simplicity sake). Do you just share each cathode of the LEDS to the common terminal im guessing?

    • 5 leds. Cathode of each led goes to its own pin (#1-5) on the resistor network. The common pin (#6) goes to ground.

  • So, I’m guessing the way to use these is put the 5 resistors inline with what you want to resist, and the common pin is the one to tie to ground?

  • 220 Ohm ones??? pweeeeeezzzze??? for the other people???

Excellent Choice

These things are awesome! They are very handy and help keep down the breadboard clutter. I wish there were more values available from Sparkfun.
