This means at 12V DC, this will draw 1A. That is three times as much current as advertised. I can not use this in my project as intended. I tried limiting it to 300 mA by putting a 24 Ohm resistor in series with it, but it would not operate, and the resistor got hot. Edit: I learned a bit more about how Solenoids are specified. That 300 mA number is how much it can continuously draw and not overheat. It will not operate at this current, but it might stay in the activated position once there at this current. I found a specification online that duplicated these specs, but included some graphs showing the rate of heating, and force VS displacement at various power levels. This Solenoid never achieves 5N at any power level shown in the graphs. I also found that this part number used to be specified up to 24V, but is now only claiming 12V operation. It might have achieved 5N at 24V. I did not see any specification anywhere for the DC resistance of the coil, a critical number if you are trying to design a circuit for this thing. People have reported measuring anywhere from 4 ohms to 18 ohms for this model of solenoid. Several manufacturers make this part number, but none specify the resistance. Unfortunately I was unable to find any other solenoid that would suit my purpose, so I will need to add an additional power supply to my design solely to support this solenoid. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07F1S3JNL | | Date First Available | October 16, 2018 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.13 ounces | | Package Dimensions | 3.7 x 3.62 x 0.43 inches | ## Images ![Push Pull Electromagnet JF-0530B DC 12V 300mA 5N 10mm 1Pcs - Image 1](https://m.media-amazon.com/images/I/61mFy-OCmKL.jpg) ![Push Pull Electromagnet JF-0530B DC 12V 300mA 5N 10mm 1Pcs - Image 2](https://m.media-amazon.com/images/I/61Kw8+oJTiL.jpg) ## Customer Reviews ### ⭐ This is a 1A solenoid, not a 300 mA solenoid *by D***P on February 11, 2021* The winding on this solenoid measures 12 Ohms.
