Laird Technologies Inc. has released its new line of EIA 0201 ferrite chip beads that extends the existing 0402 to 3312 surface-mounted monolithic EMI suppression product families.

The LI0201 chip beads' smaller, miniature foot-print make them suitable for advanced handheld electronic devices such as cellphones, Bluetooth handsets, PDAs, GPS, MP3 players, digital camcorders and digital cameras.

The series offers superior impedance versus frequency characteristics with low DCR for EMI noise suppression on high-frequency or broadband digital signal lines. The rugged monolithic assembly and 0.6mm x 0.3mm x 0.3mm foot-print offers approximately 40 percent mounting space savings over the existing 0402 products, making the LI0201 Ferrites suitable for dense, compact circuit board construction. The chip beads provide EMI noise filtering and space efficiency and can be placed close to the EMI source or receptor of the external interface or the internal signal interconnection.

"Our new ferrite chip beads meet today's trend for smaller, yet powerful, electronics for portable devices such as cellular phones, gaming devices, and other applications," said Davis Huang, Laird product director, signal integrity products. "This trend requires manufacturers to continually increase the number of mounted components in a smaller space. Laird Technologies is committed to expanding its EMI solutions portfolio to address such needs"
