This is a chart showing the difference of common mode impedance. By contrast the single choke or single winding inductors have just the one winding on the one core.

A Brief Introduction To The Common Mode Choke And Its

High Current Power Inductor Choke Coil Common Mode Choke

Coilmaster Inductor Catalogue
The we exb series common mode chokes are current compensated common mode chokes with two cores mnzn and nizn for network applications with a wide variety of interface suppressing features across a broad frequency range.

High current common mode inductor. Inductors high stability common mode choke key benefits rated for currents up to 8 a provides noise suppression for dc power lines smd construction base terminals are treated allows for easy mounting on pcb paired wire coil for high stability optimized for transmission of high quality signals. Lmlp d series of smd power inductors are designed for applications requiring high current in small low profile packages. We have complete production line in field of high current power inductors could use to design in power supply inductor smd high current inductors high saturate current inductor high power indctor surface mount inductor or other circuit which may require a power inductor.
High current common mode emi suppression inductors surface mount pico surface mount units utilize materials and methods to withstand extreme temperatures of vapor phase ir and other reflow procedures without degradation of electrical or mechanical characteristics. A common mode choke needs to have excellent noise attenuation over a wide frequency range have low capacitive coupling and handle your full load rms current without overheating. Our standard product offerings provide great value with superior performance at a low cost.
High current smd shielded power inductors with a homogeneous iron powder core construction. Coilmaster electronics established in 1995 the professional manufacturer for various kinds of passive component such as smd type of inductorsmd power inductors high current inductor also known as surface mount inductor power inductor high current power inductor through hole inductor radial leaded inductor common mode choke transformer lan magnetics. Inductance ranges from 01 to 47 uh and saturation current ranges from 3 to 120 a.
Obviously a common mode choke would have common mode impedances to suppress unwanted common mode noise. Common mode choke with differential current the common mode cm choke where two coils are wound on a single core is useful for suppression of electromagnetic interference emi and radio frequency interference rfi from power supply lines and for prevention of malfunctioning of power electronics device. Common mode cm noise current is typically radiated from sources such as unwanted radio signals unshielded electronics inverters and motors.
A common mode choke is an electrical filter that blocks high frequency noise common to two or more data or power lines while allowing the desired dc or low frequency signal to pass. Wurth electronics high current power inductors and common mode chokes are listed in leading semiconductor manufacturers application designs.
