EXC24CB chip bead arrays
Article Abstract:
Matsushita Electronic Components has unveiled the EXC24CB221U and EXC24CB102U dual-mode chip arrays that have the smallest dimensions in their class. Both arrays occupay just a fifth of the space of 1005-format, pi-style chip filters. The two devices use magnetic and capacity coupling to remove normal and common-mode noise in mobile equipment. Matsushita used lead-free plating and electrode materials for a more environment- friendly design.
