- Power Resistor Kit - 10W (25 pack)
Holy Wattage, Batman! This Power Resistor Kit comes with 5 each of 5 different 10 Watt resistor values including 1 Ohm, 2 Ohm, 4 Ohm, 8 Ohm, and 16 Ohm. These resistors are capable of dissipating large amounts of power without damaging themselves. This kit is perfect for testing projects that require large amounts of power while only requiring low resistance.
This kit comes in a box of 25.

Core Skill: Soldering
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

4.5 out of 5
Based on 2 ratings:
As advertised, but big
I'm using them with some LEDs and an lm317t to create a constant current source. I'm using the 2Ohm ones. They are working great, and they are never even warm. Beware though, each one is about two inches long.
Just what I was looking for
This pack of resistors was just what I wanted to add to my parts box. I needed to discharge failed LiPo batteries in a short time, for disposal. So far I only used one of the resistors. The kit is a fine assortment.
What are the dimensions of these? No data sheets?
I'd love to see a semi-decimal set of these too! 0.5, 1, 5, 10, 50, 100 Ohms
I used this as a heating system for my club's weather balloon. Failed mid-flight and my sensors failed about an hour in. 0/10 would not recommend for aerial vehicles.
Resistors aren't designed to be heating elements... maybe this would be better?
what is their tolerance rating?
power resistor code demystified: 10W1RJ
10W = 10 Watts dissipation (maximum, under typical mounting conditions)
1R = 1 Ohm. This kit includes other values, they'd be 2R, 4R, 8R and 16R.
J = 5% tolerance. (F = 1%, K = 10%)
Just what I need for my thermal heating pad... normal resistors burn up in a matter of seconds.
Just a word to the wise, if you are using resistors as heaters, I wouldn't recommend running them at 10 watts if that is their max power rating. They probably won't last long if you do that. 75% should be your max under normal conditions.
These are better for things like "dummy loads", current sensing/limiting, and other medium to high current applications. Though they may work well enough as heaters, they may not be designed to deliver the majority of their heat to whatever they are attached to.
The wattage rating is more of an upper limit as to how much current/voltage you can run through it without breaking it, not necessarily a measure of their "heat output" as it would be for heating device.
