SF-COM-11508

1/6th Watt, +/- 5% tolerance PTH resistors. Commonly used in breadboards and perf boards, these 10K resistors make excellent pull-ups, pull-downs, and current limiters. We’ve opted for a new and more breadboard-friendly lead thickness (they’re a bit thicker than our last ones).

PL-1166

SF-COM-00096

Electrolytic decoupling capacitors 100uF/25V. These capacitors are great transient/surge suppressors. Attach one between the power and ground of your project to ensure smooth power delivery. High quality radial electrolytic capacitors.

SF-COM-10969

Resistors are a good thing, in fact, they’re actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear into thin air. The only way to be sure that you’re gonna have the resistor you need when you need it is to stock up, and keep them o...

SF-COM-00523

Low-profile electrolytic decoupling capacitors 10uF/25V. These capacitors are great transient/surge suppressors and work well as charge pump caps for MAX232 circuits. High quality radial electrolytic capacitors.

AF-3395

This Panel Mount Right Angle 10K Linear Potentiometer w/ On-Off Switch is a two-in-one, with both a breadboard-friendly potentiometer and a switch. For the potentiometer-half, you've got a standard linear taper 10K ohm potentiometer, with a grippy shaft. It's smooth and easy t...

SF-COM-10926

Schottky diodes are known for their low forward voltage drop and a very fast switching action. This 1A 40V Schottky diode is ideal for use with motor drivers such as the L298N.

SF-COM-10856

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 10K Ohm resistors that share a common terminal on ...

SF-COM-08589

This is a simple, very common rectifier diode. Often used for reverse voltage protection, the 1N4001 is a staple for many power, DC to DC step up, and breadboard projects. 1N4001 is rated for up to 1A/50V.

AF-3391

This potentiometer is a two-in-one, good in a breadboard or with a panel. It's a log taper 10K ohm potentiometer, with a grippy shaft. It's smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-points...

SF-COM-08982

Electrolytic decoupling capacitors 1000uF/25V. These capacitors are great transient/surge suppressors and work well in high-voltage and audio applications. High quality radial electrolytic capacitors.

AF-2195

We like capacitors so much we made a kids show about them.   They're super handy and it's really helpful to have a variety lying around to pick and choose from.

SF-COM-00746

Yes you read that correctly - 10Farad capacitor. This small cap can be charged up and then slowly dissipated running an entire system for hours. Combine two in series for 5F/5V. Do not over voltage or reverse polarize these capacitors.
