Flat/plate-like magnetic powder! Effective for NFC (13.56MHz RF-ID) and electromagnetic wave absorption in electronic devices such as smartphones!
The magnetic powder "JEMK" is a soft magnetic powder manufactured by processing special alloy powder into a flattened shape. It is designed to have a high real part of permeability (μ') and a low imaginary part (μ'') in the communication frequency band of 13.56 MHz. Due to its excellent properties, it is actively used in the field of EMC and is widely utilized for NFC and electromagnetic noise suppression in electronic devices, including smartphones. 【Features】 ■ High aspect ratio soft magnetic metal powder ■ Excellent magnetic properties ■ Magnetic field convergence and magnetic responsiveness due to μ' ■ Enables long-distance communication in the 13.56 MHz band ■ Electromagnetic wave absorption due to μ'' ■ Suppresses electromagnetic noise in the hundreds of MHz to several GHz range For more details, please refer to the catalog or feel free to contact us.
