Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor or a run capacitor. Some motors will even use both.

SMD Transmitter layout The figure below shows the layout of the PCB and it uses surface-mounted devices like resistors and capacitors (non-polar devices). All the caps are size 0805 and all resistors ...

[K6ARK] likes to operate portable, so he puts together very lightweight antennas. One of his latest uses tiny toroids and SMD capacitors to form trap elements. You can see the construction of it i… ...
