Power Line Filter Modules are electronic devices used to suppress or reduce the noise and electromagnetic interference on the power line. They are widely used in systems that process electrical signals including computers, power supplies, telecommunications, industrial control, and medical equipment. B84299D1630E1 is one of the most popular Power Line Filter Modules of EPCOS, and it boasts merits such as improved EMC performance, low cost, and easy operation.

Application Field

The B84299D1630E1 is particularly well suited for applications requiring minimal interference for noise sensitive equipment, such as medical systems, telecommunications, and industrial control systems. The Power Line Filter Module is capable of attenuating common-mode EMI, thanks to its capacitive-inductive construction and filtering structures. This allows it to suppress interfering EMI signals over a wide frequency range.

Working Principle

The B84299D1630E1 uses a combination of capacitive and inductive components to filter out EMI and noise on the power line. The capacitive components consist of a series pair of capacitors in a Y configuration, where each capacitor is connected between the i/o terminals of the power line filter module and the line ground. The inductive components are constructed from toroid cores that are wound with insulated wire. The toroids are connected in series with the capacitors and are oriented with their magnetic fields cancel one another to form an EMI shield.

The B84299D1630E1 also utilizes a unique impedance matching topology that helps improve its performance. The impedance matching topology consists of a series-bonded combination of resistors and capacitors, which provides an AC impedance path between the i/o terminals and the line ground. The active components are placed in parallel so they are in balance with the capacitive and inductive components on the power line. This arrangement helps reduce the amount of interference that can pass through the filter module.

Conclusion

The B84299D1630E1 Power Line Filter Module is a highly advanced and reliable component ideal for use in systems requiring minimal interference. It boasts features such as improved EMC performance, low cost, and easy operation; as well as its capacitive-inductive construction and impedance matching topology. The B84299D1630E1 is a great choice for those looking to reduce noise and electromagnetic interference on the power line.
