Product Description for KEMET FLEX SUPPRESSOR Magnetic Sheet for RFID
The YAGEO / KEMET ELECTRONICS part number RM4A(025)-220X185T0800 is a high-performance magnetic sheet designed for RFID applications. Manufactured in Japan (COO: JP), this product is ideal for enhancing RFID communication range by preventing interference between loop antennas and metallic objects.
Key Features:
Flexible polymer-based magnetic sheet with micron-sized magnetic powders dispersed throughout
Improves magnetic flux convergence, increasing relative permeability (u’)
Low magnetic loss (u”) for efficient RFID operation
Effective carrier frequency of 13.56 MHz and below
Resistant to shock and not brittle, suitable for portable equipment
Easy to cut into various shapes and sizes
Can be laminated to RFID tags and integrated into device designs
This magnetic sheet is suitable for use in RFID tags, contactless IC cards, RFID readers/writers, and RFID-enabled devices. Its flexibility and ease of installation make it an excellent choice for improving RFID communication distance and reliability.
For more detailed specifications and application guidance, please refer to the Datasheet.
Note: The product's RoHS compliance and halogen-free features ensure environmentally friendly and safe usage.
