FLEX SUPPRESSOR® Magnetic Sheet for RFID Handling Precautions Avoid high temperature, humidity and direct sunlight. Storage environment should be below 40°C and below 70% relative humidity. The surface resistance value listed in this catalog is a reference value of the circuit parameter to indicate noise suppression. The value does not represent the product’s insulation characteristics. The value may become lower if an excess pressure is applied to the product.
