The Murata Electronics BLM18KG series (0603 size) power ferrite beads offers design engineers numerous benefits including high current capacity, excellent noise suppression and low DC resistance. This power ferrite bead is ideal for a wide range of applications including power line filtering for DC power lines in Telecommunications, Industrial Controls, PC Peripherals, White Goods, Networking and Portable Electronic Equipment. Compared to conventional 0603 size ferrite beads, the BLM18KG series can manage 1.5 to 2 times the rated current and is capable of handling up to 6 amps. Murata Electronics 0603 sized power ferrite bead can offer comparable performance to larger more expensive 0805 and 1206 power and wire wound ferrite 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 resisistance for the BLM18KG series is approximately 50% lower than conventional ferrite beads (.007 ohms to .150 ohms). There are eight parts in the series from 26 ohms to 600 ohms all having a wide operating temperature range from -55 to +125°C . Aside from the BLM18KG series, Murata Electronics offers numerous surface mount ferrite beads and noise suppression products for power related applications.
