Capacitor - Variable, Single, 365 pF, CW Rotation

Très pratique

Arrived (very quickly!) just as described and rotates smoothly 180 degrees, varying the capacitance from 0pF to 362pF per my LC meter.A standard 1/4” shaft (round with a set screw) plastic (or other nonconductive) knob is highly recommended.I used this capacitor to build a simple crystal radio on a wooden board with my kids. Worked GREAT!Couple of things that surprised me and hopefully will save you some grief and help you make best use of this nice capacitor...1) Note that all four terminals are one node (one side of the capacitor) and the metal frame is the other node. Maybe this was obvious to most, but it took me a bit to discover. If I hadn't had an LC meter to figure it out, I'd likely have assumed that the two terminals on one side were node1 and the two on the other side were node2... and then spent lots of time wondering why my circuit wasn't working!2) I mounted the capacitor to the board using the 4 #6-32 threaded holes on the bottom of the capacitor. I discovered that when the screws are tightened, the wood applied upward pressure to the two perpendicular terminal boards on either side (they extend just slightly below the metal frame), thus deforming the stationary plates of the capacitor which prevented the shaft plates from rotating without friction. I don’t think this is a design flaw at all but, clearly, if using the threaded mounting holes on the bottom, a small spacer (only about 1/16" or even 1/32”) is required between the metal frame and the wood (within/between the edges of the terminal boards) to prevent pressure on the terminal boards from the wood. FYI, after the initial deformation I was able to remedy the problem by gently shifting the terminal plates back down to their original position with a pair of needle nose pliers and the shaft now rotates freely again. (Sorry if that description isn’t clear; hopefully it will make sense once you have the capacitor in-hand and can avoid the mistake I made.)

The capacitor was very well packed and arrived perfect. It is a quality item.

Works great

Brand new, smooth rotation, works in crystal radio perfectly. I purchased two for the construction of two crystal radios for grandson and friend. Nothin’ more to say. Perfect — couldn’t be better.
