Precision Multi Turn Wirewound Potentiometer With A03 Knob (2Pcs) - 3590S Rotary Potentiometer 1K Ohm, 10-Turn Wire Wound - 3590S-2-102L Review

I like that these came with Knobs that fit the potentiometers, they are of excellent quality with high percision! I will be using these for an adjustable voltage regulator that uses TL431 adjustable reference source.

These seemed fine until I installed them and realized that the four that I bought were somehow all defective. I was trying to diagnose a problem with the project these were installed on, then got frustrated and left the project alone. Once I got back to the project and found that these potentiometers were not working properly, it was too late to return and I can't find how to contact the seller. Either there was a bad run of there or they are just cheap garbage. Either way I would steer clear…

For the price of this product, you can safely say that you are getting a good deal. Quality made, and function wonderfully

Love these 10 turn pots. They really provide the ability to control voltage/current to a high degree of resolution. And they are reasonably priced !

Nice quality. I wish it came with some instruction as there are 3 wire connection points, but I was able to figure out which two to use with a multimeter.

These were installed in a bench power supply to get a "fine" control of voltage and current limit. They worked just fine for a while, then started to get sloppy holding their value - just like an old volume control in a vintage stereo. Inexcusable. The Chinese are incapable of making any kind of lasting electrical connections - as we've all seen it so many times before.

Lightning hit our gate opener, TWICE! Each time, along with a fried circuit board in the control box, a potentiometer in the actuator arm was blown apart. These have the same specs, but not a flatted shaft. A grinder and file made them fit in place, and after soldering on wires and reassembling, I have 2 working actuator arms again. (saving me hundreds of dollars)

Although these pots work great, one of the 4 I ordered was bad. The working pots work great and did my job as required. That's my review!

Steady resistance control, doesn't jump around. Its wirewound, not a carbon strip, so it has a ribbed feel to the action, not a bad thing. I used for dimming 12V/12W led lighting strip, works great.

These things come with all the attachment gear, and nice dials as well. These are great.! I Ohm'd them out and they are correct.

I received the 10-turn pots with knobs, but there was only one knob setscrew loose in the package. I wrote asking to get another setscrew, but received no reply

On the normal potentiometer, the two pins that connect to the end of the track or typically on the outside edges, and the pin that is connected to the wiper of the potentiometer is in the middle. On this potentiometer, the pin that is connected to the wiper is on the end farthest from the knob. There is a small diagram I did not see at first on the side of the potentiometer and I wired it up wrong making me think it was defective. And upon closer inspection and testing I was able to find the…

good thing you get two, because one was defective. Poor quality. No more radio shack, so you have to order from Ebay and hope. Also, you'll need to buy extra washers for the "back" of the threaded shaft, not included. In our case, we stole the hardware from the second junk pot. Couldn't return, since it was already soldered in place.
