Uxcell a15102800ux0071 3 Piece 224pF 4 Linear PCB Trimmer Tuning Variable Adjustable Capacitors for Radio

Q: How do I adjust the capacitor? Do I need a 1.25 mm pin for it, or how does it work?

Use a small straight blade screwdriver. You can see the head in the photo.

Q: Can I wire the capacitor to a breadboard? How? Please be specific...

It's a little complicated! The two corner pegs that are connected to the silvery bits are the poles of two separate capacitors, which can be adjusted individually with the screws in the center of those silvery bits. The control on the other side adjusts both simultaneously. The two rectangular tabs are electrically connected to one another, and are a shared pole of both capacitors. The other two corner pegs don't seem to be connected to anything. It's hard to plug this directly into a breadboard, I would recommend connecting it via wires.

Q: How do you connect this to a breadboard via wires? Please Im not looking for explanations of parts, just need to know where to connect what to what.

Hello Anh, The uxcell 224 pf trimmer caps weren't ready for use when I received them. 1. I had to adjust the capacitance value until I got the correct amount which took about 20 minutes. 2. to use them on a breadboard, I had to solder a longer wire onto each pin. Good luck.. I hope I've helped. I found much better variable caps on Ebay at Ross1Charter. answer from Steve

Q: Any idea where I can find a wheel or knob to fit the main shaft of this? The shaft has a flat side and a screw hole in the center.

Warning!!! These are not 224 pf but only about 20 at max!!!

3.6/5
