Würth Elektronik WE-CBA SMD EMI Suppression Ferrite Beads
Würth Elektronik WE-CBA SMD EMI Suppression Ferrite Beads are AEC-Q200 qualified and can be put directly onto a printed circuit board. These ferrite beads offer excellent anti-EMI properties and low DC resistance. When placed close to the interference source (even with the smallest size of 0402), the maximal impedance at 1000Ω can be reached. Würth Elektronik WE-CBA series ferrite beads are ideal as data filters for the uncoupling of distribution voltages. Other applications include USB 2.0, control signals, RS232, RS422, DC/DC converters, and power supplies.
Components
- High-speed SMD ferrites have a lower impedance in the lower frequency ranges, giving them a low attenuation for fast signals. Applications include USB 2.0, IEEE 1394, and LVDS.
- Wide-band SMD ferrites (WE-CBF) show high impedance in the low-frequency range, making them wide-band through the whole spectrum. Applications are control signals, RS232, RS422, and DC/DC converters.
- High-current SMD ferrites are designed for high currents over 1A. The rated current refers to 40K self-heating. High-current SMD ferrites are available in all three types (high speed, wide band, and high frequency). Applications include power supplies and DC/DC converters.
