Electromagnetic Wave Noise Countermeasure Sheet
A rich lineup tailored for high heat resistance and electromagnetic environments.

【Noise Suppression Sheet】 - Converts noise into heat through magnetic loss of magnetic powder. - The higher the permeability and the thicker the sheet layer, the greater the noise suppression effect. - Has an adhesive layer for direct attachment to noise sources. - Flexible, allowing for attachment to uneven surfaces and cables, and can be cut to size. ■ Lineup MF: Supports 3MHz to 3GHz, permeability 200, -40℃ to 125℃, equivalent to UL-94 HB. HF: Supports 300MHz to 30GHz, permeability 30/10, -40℃ to 125℃, equivalent to UL-94 HB. UF: Supports 3GHz to 40GHz, permeability 10, -40℃ to 125℃, equivalent to UL-94 V0. 【Radio Wave Absorption Sheet】 - Absorbs radio waves by canceling primary and secondary reflection waves. - Demonstrates radio wave absorption properties when used in conjunction with a metal reflection layer. - Has an adhesive layer for application to targeted areas. - Flexible and can be cut to size. - Heat-resistant for automotive applications. ■ Lineup Four types: 28GHz, 38GHz, 60GHz, and 77GHz (other frequencies can also be accommodated). *All sheets absorb more than 20dB, -40℃ to 125℃, equivalent to UL-94 HB.
