Manufacturers of handheld devices specifically benefit from Murata's BLM18SG series low DC resistance because it enables a low voltage drop that reduces power consumption. The DC resistance for the new BLM18SG is approximately 50% lower than conventional ferrite beads. By using less energy, the product's battery life is significantly extended.
Another benefit for design engineers is the ferrite bead's ability to meet the demands for faster processing and increased current requirements. Compared to other 0603-sized surface mount ferrite beads, the BLM18SG can handle up to 6A. This feature is particularly important because it helps manufacturers meet FCC regulations regarding noise suppression for high current power lines. These FCC requirements were estabilshed to prevent an increase in electromagnetic interference (EMI) from the dramatic influx of equipement use such as computers and fax machines in both homes and offices.
Murata offers numerous noise suppression products "EMIFIL" (electromagnetic interference filters) that are designed for use on signal lines and in power supply and general electronic circuits. The EMIFIL product range includes ferrite beads, ferrite cores, common mode chokes and a variety of other components to effectively suppress noise.
