Murata Introduces High-Current, Low Cost Power Ferrite Bead - Component Provides Excellent Noise Suppression and DC Resistance for DC Power Line Filtering
Smyrna, GA, February 17, 2009 – Murata Electronics North America, a world-leading innovator in electronics and the largest global supplier of ceramic passive components, today introduced a new high-current, power ferrite bead to its BLM series. The competitively priced BLM18KG series 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 such as 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,” stated Deryl Kimbro, product manager 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.”
The BLM18KG has a sample price of $0.05 with an average lead-time of approximately six to eight weeks. Additional purchasing info can be found on-line at www.murata-northamerica.com.
Aside from the BLM18KG, 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. Murata also provides technical support and guidance based on years of experience operating in the field of noise suppression. The technical support includes design kits, application manuals and a comprehensive set of software tools to simulate virtually any circuit condition.
