Murata Electronics North America recently introduced what are reportedly the world’s smallest ferrite beads, measuring only 0.4 x 0.2 x 0. 2mm. The 01005-sized BLM02 series is ideal for noise suppression use in electromagnetic interference (EMI) filter applications and DC power lines, which are found in numerous electronics like RF modules, laptops, portable music devices and car navigation systems.
In addition to the benefit of their small size, which conserves valuable board space, the new ferrite beads do not compromise performance. As part of Murata’s electromagnetic interference filter (EMIFIL) family of chip ferrite beads, the BLM02 provides a wide attenuation frequency range, approximately 30 MHz to several hundred MHZ, and an impedance range of 10 to 120 Ohms with rated currents between 200 and 500 mA. The 01005-sized beads also offer DC resistance below 0.8 Ohms and operate between 55 and 125ºC.
“Murata’s expertise in advanced materials allows for smaller and smaller products that do not sacrifice functionality or needed characteristics,” said Deryl Kimbro, product manager EMI filters and chip inductors for Murata Electronics North America. “The new ferrite bead series is a perfect example of Murata’s knowledge and commitment to quality components.”
