Taiss 2pcs 3590S Rotary Potentiometer 5k ohm Potentiometers 10-Turn Wire Wound Precision, Precision Multi Turn Wirewound Potentiometer+ 2pcs A03 knob (3590S-2-502L 5k ohm)

Update: I cracked one of these open, and by gosh, they ARE wire wound. I upgraded my 4 star up to f5. Some of the concerns below are still in play, but the potential issue as to weather or not they are wire wound has been put to rest. Original Review: Not exactly sure what they actually are. I needed a fairly large number of Bourns 3590 multi turn pots. But they are very pricey, and if you need quite a few of them, it starts to add up. I checked to make sure they were functional, and they were. However, I also have some real Bourns 3590 pots, and they are not exactly the same, even though they look the same. The shaft on these pots offers resistance to turning, while the real Bourns pots rotate freely. Also, as you turn these pots, they feel smooth, where as the real Bourns pots will give a very slight sensation as the wiper rides over the wire wound element. Despite the claim, I have serous doubts about the claims that these are wire wound. These came from China, and so did others that I purchased from various sources. The funniest one had the name Bones on it rather than Bourns. And prices vary. I found one seller that was selling them for just a bit more than a dollar. All come from Asia, and are probably made in the same factory. I have no idea what kind of endurance they might have. I am strongly tempted to break one open to see what they really are. Still, I give them a 4-Star rating because they will do the job I want them to do. However, for more critical applications I will stick with real (and expensive) Bourns pots from authorized distributors.

Examined and installed: appears well-made and fairly sturdy; functions smoothly, turns easily; plastic shell didn’t melt when heavy wire was soldered to a lug; measures 507 ohm, well within stated tolerance. It will be operated near its 2-watt rating at times, so we’ll see how well it tolerates that.

If you're looking for a basic potentiameter, this is a quality, small one. I like it, it works well. The only con that I could find is the fact that it doesn't have a dial that tells you what level it's on. If that's not something you require, then this is a good item.

The quality is perfect I been using it for a year now never had a issue I used it for my alternator on my car to turn the voltage up and down

I got two of these 10k, ten-turn potentiometers to upgrade my workbench DC power supply. The original voltage pot was scratchy and the current pot was only 3/4 turn. There was plenty of room inside the panel, but I did have to drill the mounting holes out a little bit. These pots worked out great. The adjustments are now even and without skips. The only snag was the knobs. They are 1 inch in diameter and the pots are an inch apart on my power supply. Since the knobs aren’t perfectly concentric, they rubbed and interfered with each other. I put one on a bit high on it shaft until I can find slightly smaller knobs or trim these down a tiny bit.

To build a "home grown" 0-24 VDC Bench Power Supply required the use of an Audio Taper potentiometer for smooth and fine adjustment of the output voltage. These type of pots are not as common as the Linear Taper and are challenging to find at a reasonable price. I only needed one and it works smoothly. The 10-turn pot allows fine voltage adjustment across the entire output voltage range. Very pleased with the price and performance!

Decent ten turn. Using in old power supply. Great control. No dropouts.

These failed as soon as we soldered a wire to one of its terminals. We used low temp solder with a temp -controlled iron: we have soldered thousands of pots this way without ever damaging them.

as advertised

muy bueno ademas incluye perillas exelente
