EMI/RFI filters are electrical devices used to suppress disturbance and control interference between two circuits. The CM1406-04DE is a common example of an EMI/RFI filter, and is used in a variety of applications. This filter has three functioning parts with distinct roles: line filters, differential modes and common modes.

The line filters of the CM1406-04DE are designed to reduce noise so that products being used in the intended application will not be hindered by any kind of interference. This kind of line filter is used to control both differential and common mode interference, and generally consist of small coils, capacitors and other components. The effectiveness of a line filter is usually judged by its ability to filter out EMI/RFI noise, and these small components are designed to improve the quality of the product.

The differential mode filters of the CM1406-04DE are designed to eliminate any differences between two electrical signals that may be travelling between two different circuits. This type of filter works by measuring the absolute difference in current between two points, and then compensating for this difference in order to reduce any form of interference. This filter also works to decrease the chances of any electrocution, fire or shock which could otherwise occur if differences in current levels remain un-monitored.

The common mode filters of the CM1406-04DE are designed to reduce any kind of common interference, i.e. interference that affects both signals in the same circuit. This kind of filter works by measuring the amount of common interference and then subtracting it from the overall signal travelling via the circuit. The common mode filters are divided into two sub-sections, in order to provide maximum coverage. These include a “low” filter that is intended to reduce noise between common-mode signals, and a “high” filter designed to reduce high frequencies.

In conclusion, the CM1406-04DE is an effective EMI/RFI filter, designed to reduce interference travelling between two circuits. This filter has three components with three distinct roles: line filters, differential mode filters and common mode filters. These components are designed to reduce EMI/RFI noise, reduce any differences in current levels between points and reduce any common interference between signals. This kind of filter is vital in controlling EMI/RFI disturbance, which can otherwise interfere with the proper function of a product or system.
