EMI & RFI Absorbers

Improve data integrity

eliminate emissions, crosstalk, and oscillations that degrade signal clarity


Increase Device Density

Place more electronics in smaller volumes without the risk of corrupting electronic signals


Electromagnetic Interference (EMI) or Radio Frequency Interference (EMI/RFI) reduces performance in sensitive electronic systems because it degrades signal strength and clarity. To prevent this interference, EMI/RFI Absorbers convert unwanted electromagnetic waves into heat in order to protect electronic device accuracy.

EMI/RFI Absorbers rely on high conductivity, high permeability, and material thickness to reduce the amplitude of errant waves that could distort signals on electronic devices. Used primarily to eliminate emissions from cables and circuit traces, EMI/RFI Absorbers are ideal for higher frequencies, especially those used in communications. Absorbers are typically highly conformable, compressible, and cushion against vibration and shock.

Boyd’s experience in integrated, multifunctional solutions includes EMI absorption systems for a broad range of applications where performance is key to a successful product. By incorporating Boyd’s EMI/RFI Absorbers into products, customers improve antenna performance, high speed communications, increase signal integrity and reduce emissions, crosstalk, and oscillations.
