Murata Electronics North America recently introduced a new high-current power ferrite bead to its BLM series. The BLM18KG series reportedly offers design engineers numerous benefits, including high current capacity, excellent noise suppression and low DC resistance. This ferrite bead is ideal for a wide range of applications, including power line filtering for DC power lines located in compact mobile equipment like personal digital assistants (PDAs), portable navigation devices, digital cameras and cellular phones.

Compared to conventional 0603 power beads, the BLM18KG can manage 1.5 to 2 times the rated current and is capable of handling up to 6 amps. Murata’s 0603-sized ferrite beads can offer comparable performance to larger, more expensive 0805 and 1206 power and wire wound beads. Another benefit to the BLM18KG series is the low DC resistance because it enables a low voltage drop that reduces power consumption. The DC resistance for the new BLM18KG is approximately 50% lower than conventional ferrite beads. By using less energy, the product’s battery life is significantly extended.

“Murata’s new power beads provide customers with better electrical performance at a lower price point than competitor products,” said Deryl Kimbro, product manager for EMI filters and chip inductors for Murata Electronics North America. “Given the current state of the economy, more features for less money is a great bargain.”
