RF Architectural Shielding Products
EMI (Electromagnetic Interference) is often used interchangeably with RFI (Radio Frequency Interference). However, EMI can be any frequency of electromagnetic noise, whereas RFI is a relatively narrow range of electromagnetic noise on the EM spectrum. EMI Shielding can be used to mitigate electric and magnetic radiation across various spaces. Radio Frequency (RF) Shielding can be used to mitigate RFI with specifically designed enclosures that can block RFI. As well, RF Shielding can include application of RF Shielding paints, fabrics, and other materials.

Drum Core Inductors
Drum core inductors are so named as the conductor (round magnet wire) is wound directly onto the ferrite core which is shaped like a drum or spool. The wire is then connected to the core, a plastic base or metal lead frame to form the surface mount termination. Drum core inductors come in unshielded (high saturation current but potentially more EMI) and shielded constructions (lower saturation current but closed magnetic path for lower EMI). The shielded constructions use either a second ferrite core or a magnetic resin epoxy to create the magnetic shield.

EMF Measurements/EM Measurements/Electromagnetic Radiation
Holland Shielding Systems B.V.
Electromagnetic fields cause interference in electronic devices and may affect the health of people close to where the fields are generated. It is important to recognize this at an early stage in a construction process, for instance at a future construction location or while construction is already underway, so that budgets are not exceeded. By means of field-strength measurements one can chart the existing electromagnetic fields and radiation emitted by GSM, UMTS antennas and transformer spaces, to mention a few examples. These measurements can help determine the best location in the new building for rooms where sensitive measurements are to take place, e.g. in hospitals or nano laboratories. And last but not least, field-strength measurements can detect sources of interference and can be part of a scheduled check of existing screened spaces and Faraday cages.
