RF shields are components which are used to abosrb/dissipate RF noise/emissions. They are used both to protect sensitive circuits from external noise and to reduce the emmisions of noisy circuits.
These are the most common types of RF shields, and are commonly just referred to as an “RF shield”. They are through-hole or surface-mound metal casings which are soldered onto a PCB, and prevent RF either getting into or getting out of the components inside the shield.
