Common mode Chokes

Inductive Components – EMC Components and Ferrite Cores

What are Common Mode Chokes?

In the transmission system, noise is classified in two ways: one is differential mode noise and the other is common mode noise. A common mode signal (noise) is an unwanted signal as it “carries” no information. A common mode choke is designed to clean common mode noise (signal) generated from either a signal line or power line circuit.

How do Common Mode Chokes Work?

Common mode chokes are used to suppress common mode noise. When a common mode noise enters a circuit with a common mode choke installed, the flux generated by the D+ signal and that by the D-signal enhance each other, generating high impedance and preventing common mode noise from passing.

How to Choose the Right Mode Chokes Work?

Firstly, understand the “problem frequency” and then check whether the key features (like operating temperature, quality requirements), key parameters and dimension (like rated voltage , rated current and Inductance /Impedance”) can meet requirements or not.

Benefits of Laird Performance Materials’ Common Mode Chokes

Constructed from ultra-thin mixtures of iron, nickel and zinc oxides, Laird Steward ferrite common mode chokes are characterized by their size, light weight, low cost, and high reliability. They provide superb EMI reduction while remaining open to normal circuit operation.

Laird chokes have excellent inductance performance even at frequencies as low as 100 kHz and below. They are built in a way where wires are wound in a circular shape called toroidal. These chokes use many pairs of cables, whether twisted together or not, which helps reduce interference and unwanted signals in wires that are usually twisted. Additionally, they can accurately handle different levels of electric current across a wide range of inductance values.

Laird chokes exhibit superior inductance performance well into the 100 kHz range and below. The internal construction of these chokes are of the wound toroidal fashion. They use a large number of cable pairs twisted or non-twisted. This configuration reduces RFI and cross talk associated with balanced wires found in most common chokes.

Ferrite Beads on Wire

Inductive Components – EMC Components and Ferrite Cores

High-powered Energy Management

If managed improperly while they are active, cords and cables on consumer electronics create radio energy, causing noise which disturbs and interferes with other nearby electronic devices. Laird Steward’s small, cylindrical ferrite beads positioned on wire enable you to block the emission of radio waves from the cords and cables, thus maximizing power efficiency. The ultra-thin, lightweight designs consist of a layered inductor structure that isolates and converts the energy into heat, creating impedance over a broad frequency range while maintaining a low-cost, streamlined system that won’t compromise your overall design or impair other surface mount devices.

Ferrite Cable Cores

Inductive Components – EMC Components and Ferrite Cores

What are Ferrite Cores?

In the transmission system, noise is classified in two ways: one is differential mode noise and the other is common mode noise. A common mode signal (noise) is an unwanted signal as it “carries” no information. A ferrite cable core is designed to clean common mode noise (signal) generated from either a signal line or power cable.

How do Ferrite Cores Work?

Ferrite cores are used to suppress electromagnetic emissions by blocking low-frequency noise and absorbing high-frequency noise. This avoids electromagnetic interference.

How to Choose the Right Ferrite Cable Core

Firstly, confirm the “problem frequency” and then the available space. The next step is to select an appropriate ferrite core (refer ID , OD and length of this ferrite core) with as higher an impedance as possible which can cover the problem frequency.

Ferrite Plates and Disks

Inductive Components – EMC Components and Ferrite Cores

Block EMI at its Source

Most consumer electronics run on flexible printed circuit boards which are designed to the exact specifications needed to meet their intended purpose. Computers and microwaves couldn’t function without properly working PCBs. Wherever EMI and active antennas disrupt the circuit board after the soldering process, Laird Steward ferrite disks and plates provide a simple, cost-effective solution. They can be utilized either as inductively coupled components or, as EMI shields on PCBs. The inductive coupling occurs when the ferrite affects the conducted wave form leaving the active component. The rise time of the wave form is effectively slowed by the ferrite. The overshoot and associated ringing are attenuated. On PCBs, they can be placed directly on the EMI source, absorbing the radiated emissions at its core. This can help streamline your design and reduce overall material cost. Simple solution. Maximum efficiency.
