EMC/RFI/IP Protection Devices
What types of electromagnetic interference do we distinguish? Electromagnetic compatibility (EMC) and the electromagnetic environment affect the connections between electrical or electronic systems and the operation of components.
There are three main types of problems that can occur individually or together:
- Conducted Interference – This results from effects caused by voltage drops, surges, pulsations, and high-frequency currents that may occur in electrical systems.
- Proximity of the device to the radiation source – Galvanic coupling has a significant impact on the nearby field associated with a given device/system. Capacitive and inductive coupling results in emission close to the source.
- Distance of the device from the radiation source – Devices located in the vicinity of an electrical system affect the interaction with the distant field, which can influence the system.
Wave Theory
An electromagnetic field source generates a field with two components: electric and magnetic. The relationship between the electric and magnetic fields depends on the type of source and the distance. The ratio of these fields determines a parameter expressed as Z – the wave impedance.
Sources generating magnetic fields are called low-impedance sources, while high-impedance sources generate electric fields.
Shielding
When a wave encounters an obstacle, such as an object, part of its energy is reflected, part penetrates the object, and some is absorbed by the object – changing into heat or internal currents. The impedance of the wave and the object is crucial. The greater the difference, the more energy is reflected. The lower the wave impedance, the more energy is absorbed, making magnetic fields difficult to shield. Any internal currents generated within a shield can create a field on the other side of the barrier, so the most effective method is wave reflection.
Our range includes: braided mesh gaskets, edge gaskets, conductive tapes, devices for shielding PCB components, plastic EMC surface coatings, conductive paints and adhesives, IP gaskets, microwave absorbers, and shielding mats, foam gaskets, conductive elastomers. You will also find semiconductors.
