EMI Filtering versus Shielding: Which is Better?

Shields and filters are both valuable tools for reducing electronic emissions caused by the EMI (electromagnetic interference). It has been found that using both is one of the most effective solutions to reduce electronic emissions. For instance, EMI shielding methods are used to overcome a range of EMI problems and can adequately reflect EMI.

On the other hand, filters help to eliminate the EMI. They help to solve issues related to penetrations through shields as well as the inputs and outputs of an electrical system. Such combination of filters and shields is contributing to the growth of the EMI/RFI filtering market. Using EMI filtering techniques, a transient suppression at a shielded enclosure interface is found to be a highly efficient way to protect against compatibility issues in several electronic machines and devices.

Automotive Components, Assemblies Trigger Demand for EMI/RFI Filters

The ever-increasing automotive industry is creating stable revenue streams for manufacturers in the EMI/RFI filtering market. Two-wheelers, cars, rickshaws, and heavy vehicles are highly dependent on electro-mechanical components and sub-assemblies. Manufacturers are boosting their output capacities to increase the availability of active electronic components in automotive range from ABS and ECO automotive powertrains, car navigation systems, safety equipment, and automotive infotainment devices.

Automotive components and assemblies tend to emit RF (radio frequency) noise, and are potentially exposed to external sources of energy, resulting in unanticipated changes in system operation. This is where manufacturers in the EMI/RFI filtering market are stepping in to boost their output capabilities for single-phase EMI filters, 3 phase filters, and harmonic filters. Vehicle OEMs are addressing issues of broadband and narrowband noises of EMI with filters build immunity characteristics in automotive systems and components.

EMI/RFI Filters in MRI Rooms, Communication Devices Transforming Electronic Applications

Shielded rooms, energy managements, and communication applications are creating revenue streams for companies in the EMI/RFI filtering market. Shielded rooms are popular in SCIFs (Sensitive Compartmented Information Facility) utilized in military applications, MRI rooms in hospitals, and server rooms for commercial businesses. EMI/RFI filters are being used in energy management systems to keep emissions from affecting sensitive equipment in smart home applications and renewable energy systems.

Communications systems such as data lines, telephones, and fire alarms are fueling the demand for EMI/RFI filters to avoid interference on the lines. EMI/RFI filters help to prevent false alarms or noise being projected over the alerting system. Electronics applications are helping manufacturers expand their business streams, since automation or test equipment electronics and laboratory equipment are integrated with EMI/RFI filters to prevent emissions.
