EMI Suppression Arrays Offer Wide Impedance Range

For space limited applications such as cellular telephones and pagers, TCA Series ferrite chip bead arrays come with impedances of 60 ohms, 120 ohms, 300 ohms or 600 ohms at 100 MHz in a surface-mount package with dimensions of 3.2 x 1.6 mm. Each array can handle four lines, supplying identical impedance to each. Crosstalk between lines is said to be minimal. Current handling range is 100 to 300 mA and maximum dc resistance range is 0.15 ohmsto 0.5 ohms.
