The cookies we create are temporary. Besides the basic ones that let us store your site preferences, some let us analyze site behaviour and some let us determine the impact of our advertising. That is, which types of ads are working and which types are not.
These cookies are essential for proper site function. They include things like the language you prefer, the country your IP address is from (so you can view the correct version of the page), and whatever cookie preferences you choose here.
These cookies help us understand behavior on our website and are critical to help us see which of our advertising and marketing efforts are working.
We advertise on a variety of platforms including social media and internet search providers. These sorts of cookies and the information we share lets platforms match you with your social media or internet search account (we can't see that information, only the platform can). That's helpful because it allows the platform to indicate whether our ads resulted in purchases or not. Then we can optimize the way we serve ads so that we aren't wasting money on ineffective ads. The platform also isn't driving you crazy with completely irrelevant ads. This doesn't make you get any more ads, it just makes the ads more relevant to you.
**Important: Choose the resistance value you want**
Overview
Spintronic resistors resist the flow of current. The higher the resistance value, the harder they are to turn. Resistors help keep circuits under control by limiting the flow of current.
Resistors come with fixed values that cannot be changed. You must choose the value of the resistor before you can add it to your cart.
Detailed description
Resistance is generated from shearing of silicone oil inside a sealed chamber. This gives a very stable resistance with low stiction. To make resistors of different values, the factory mixes silicone oils of varying viscosity.
Resistances are accurate to +/- 10% at the reference spin voltage. Note that there is a significant dependence of resistance on the spin voltage applied across the resistor due to the slight non-Newtonian behavior of silicone oil. See the datasheet supplied with the part for more information.

I have a class set of 6 Spintronics sets. The 1000 Ohm resistors were breaking for whatever reason (my students or a design flaw). I contacted Upper story about getting replacement parts. They replaced all 6 of the 1000 Ohm resistors, no questions asked. It was a dream working with them. Thanks again!

Your service on replacement parts is excellent

Great learning tool.
My students get a free choice of resistors to use during challenges. Many make use of that and have learned the importance of resistors.

Love Those Spintronics!
My fourth graders can't keep their hands off of the Spintronics! So much fun!
