A ferrite bead or ferrite choke is a passive electric component that suppresses high-frequency noise in electronic circuits. It is a specific type of electronic choke. Ferrite beads employ high-frequency current dissipation in a ferrite ceramic to build high-frequency noise suppression devices.

Free ferrite is ferrite that is structurally separate and distinct, as may be formed without the simultaneous formation of carbide when cooling hypoeutectoid austenite into the critical temperature range. Free ferrite is a relatively pure metallic iron phase present in steel or cast iron.
Ferrite rod aerials (or antennas) are a type of small magnetic loop (SML) antenna very common in AM radio broadcast band transistor radios, although they began to be used in vacuum tube ("valve") radios in the 1950s. They are also useful in very low frequency (VLF) receivers, and can sometimes give good results over most of the shortwave frequencies (assuming a suitable ferrite is used).
necting the mic to the input gear was wound around a toroidal ferrite (Fig 1) to form an RF choke that reduces that current. Fig 1 – A toroidal ferrite choke Fig 2 – Ferrites are made in many forms To test the effectiveness of ferrite chokes in audio RFI applications, selected product sam-ples were ordered, and a series of tests were run.
May 03, 2014· Ferrite is defined as the solid solution of carbon in iron. What do we perceive from ferrite number in welding? Ferrite number is the amount of retained delta ferrite into the weldment of austenitic stainless steels, which may support mechanical and corrosion properties (if present within the acceptable range). Ferrite number approximates 5-20.

Ferrite is a magnetic material comprising of iron oxides, nickel, zinc and other compounds like manganese. Ferrite cores are distinguished from other ferrite devices like magnets in that they are made from a softer material, referred to as soft ferrites as opposed to hard ferrites.
The TUB4/2/5-3B1 is an EMI-Suppression Tube can be used in solenoid coils with almost the same effect as rods. The inner hole is often used to insert wires to make a ferrite coil former. In EMI suppression applications tube can also be shifted over wires. Because the magnetic flux path is then closed, a steep increase in impedance results.
Ferrite Content in Austenitic Stainless Steels The basic 300 series stainless materials like 304/L and 316/L have an austenitic microstructure and are non-magnetic. That is, in the annealed condition they are essentially free of ferrite, which is magnetic.
