What is the difference between ferrite bead and an inductor and On what basis they have to be selected?
Ferrite bead is a lossy inductor.When the frequency is high the Ferrite bead purely acts as a resistance so high speed noises are absorbed by the FB and it dissipate in the form of heat.
Based on the current rating,cross over frequency the ferrite bead should be select
ANSWER: A ferrite bead is a powder core if a line is wrapped on it that will eliminate RF signal externally injected into the line to interfere with the circuit that the line is going to it. The selection is arbitrary until it does the job. bigger the better. An inductor is also a choke to reduce RF but not as effective and it does have losses on the line

How to measure the ferrite number?
You can measure the ferrite number of a steel using a Severn Gage, a mechanical device; or using a ferrite scope, an electronic device, available from several manufacturers.

dual phase steel is a high strength steel that has a ferrite and martensitic microstructure
Working of a capitance and coil?
A ferrite core inductor with two 47 mH windings. An inductor usually consists of a coil of conducting material.
What is the basic Difference between ferrite core and normal transformer?
i think Transformer operates AC and ferrite core operates in DC
Details about ferrite core inductor?
Ferrite core inductors are made for higher frequencies. The ferrite core is a non-conductive ferri-magnetic material which prevents eddy currents from flowing through it. The ferrite formulation is xxFe2O4 with the xx representing various types of metals.
What is the difference between pearlite and ferrite?
Pearlite is a layered structure of ferrite and cementite formed by the eutectoid reaction in steel, while ferrite is a pure form of iron in its BCC crystal structure. Ferrite is soft and ductile, while pearlite is harder due to the presence of cementite.
What is the difference between pearlite and cementite?
Well, basically, pearlite is the eutectic composition of steel, with an overall composition of 0.8% carbon. It is known to consist of two phases, namely: Ferrite (Fe), the room temperature of iron and Cementite(Fe3C). Therefore, the difference between pearlite and cementite is that pearlite is a composition of steel, and cementite is a composition of Pearlite. So cementite is part of pearlite.

Difference between AI SI 409 m and ss 409 m?
SS 409M is the modified ferritic stainless developed from AISI 409M by using the kaltenhauser ferrite factor(KFF). The grain growth in HAZ is minimized by the increased amount of martensite by combination ferrite and austenizing stabilisers using the above relationship.
What is the difference between an alnico magnet and ferrite magnet?
The term alnico is derived from the names of three metals, aluminum, nickel, and cobalt, which can be used to make an alloy that has useful magnetic properties. Ferrite is a form of iron. Alnico magnets are more powerful and more expensive than ferrite magnets.
How do I convert a Ferrite number into a percentage?
While there is no direct correlation, with higher ferrite numbers ( >30) a factor of 0.7 can be applied to produce % ferrite.
What is ferrite number?
Ferrite number is a measure of = Chromium & Nickel equivalent in an Austenitic stainless steel material. It should be between 3-7% max. Very low ferrite can lead to cracks. It is a measure of denoting the ferrite content in an stainless steel. Ferrite Number has been adopted as a relative measure for quantifying ferritic content using standardized magnetic techniques. The Ferrite Number approach was developed in order to reduce the large variation in ferrite levels determined on a given specimen when measured using different techniques in different labratories.The ferrite level is only important to assure minimum exposure to solidification cracking when depositing austenitic stainless steel weld metal. The lower ferrite number is better for corrosion resistance, while balancing higher ferrite content to avoid solidification cracking in the weld deposit. I would not worry about lower ferrite numbers for clad overlay welding, if no cracking is observed (Liquid Penetrant verification).
What color tube for ferrite?
Typically, ferrite cores are available in various colors, depending on the material composition used. Common colors include black, grey, and blue. The color does not indicate a specific functional difference but rather is for identification and aesthetic purposes.
