Common Mode Chokes (CMC) are a type of specialized electrical component used in electronic circuits to reduce common mode noise. The most common type of CMC used is a ferrite toroidal core. This type of core is composed of a magnetic material that is wound with two or more insulated wires. CMCs are primarily used in power supplies, motor drives, motor controllers, automotive applications, and more. While CMCs have many uses, one of the most notable uses is in the filtering of high frequency digital signals and in the reduction of electromagnetic interference (EMI) for radio frequency (RF) circuits. The LCF121002B350TG is one example of a CMC specifically designed for such applications.

The LCF121002B350TG is a ferrite core common mode choke. It is designed to provide efficient EMI reduction, with minimum insertion loss and optimum common mode suppression. This product consists of two identical windings, each with a core diameter of 12.7mm. The two windings are surrounded by an outer core of ferrite material. This type of core has a rated DC current of 350mA and a rated temperature range of -40°C to +105°C.The LCF121002B350TG is UL recognized.

The LCF121002B350TG is used to reduce radiated emissions and protect against interference in electronic circuits. This is accomplished by blocking or filtering out signal components that may be interfering with the circuit’s operation. This type of CMC can also be used to attenuate high frequency noise in the system, which is caused by components such as motors, transformers, power supplies, and other electronic devices. The LCF121002B350TG is particularly useful in applications that require robust EMI and RFI suppression, such as medical, automotive, and communications systems.

The LCF121002B350TG works by utilizing the core material’s electromagnetic properties. When connected in an inductive or capacitive circuit, the two windings create a magnetic field that is capable of blocking out unwanted signal components. The majority of the choke’s common mode noise is suppressed by its overall inductance, while the outer core material functions to reduce the amount of magnetic flux leakage from the windings. By utilizing this combination of inductive and capacitive properties, the LCF121002B350TG is able to effectively reduce the amount of interfering EMI and RFI signals.

The LCF121002B350TG is a versatile and highly reliable EMI suppression device. It is designed for use in a wide range of applications, from automotive to communications systems, and is especially suitable for products that require robust features and protection. With its rated temperature range and UL recognition, the LCF121002B350TG is an ideal choice for high-quality EMI and RFI suppression.
