Tiny ferrite bead boasts high impedance

31 October 2007 Passive Components

Murata has developed a chip ferrite bead, the BLM03AG102SN1, claiming the industry's highest impedance in the 0603 size, at 0,6 x 0,3 x 0,3 mm (L x W x T). The new module, with impedance of 1000 Ω (at 100 MHz) joins the existing products in the BLM03A series, with impedances of 10, 70, 120, 240 and 600 Ω (at 100 MHz) for noise suppression on general signal lines and EMI suppression for various types of electronic equipment.
