742861210

The 742861210 is a surface-mount ferrite bead from Würth Elektronik, part of the WE-CBF HF series. It provides a nominal impedance of 1000 Ω at 100 MHz, with a typical impedance of 1100 Ω at 1 GHz and a maximum impedance of 2200 Ω at 450 MHz. This single-line signal filter is designed for high-frequency EMI suppression in compact electronic assemblies.

The component has a maximum DC resistance of 1.8 Ω and a typical DC resistance of 1.2 Ω at 20 °C. It is rated for a maximum current of 50 mA at a temperature rise of 20 K, and up to 300 mA at a 40 K rise. The ferrite bead is housed in a 0603 (1608 metric) package with surface-mount termination, measuring 1.60 mm by 0.80 mm with a maximum height of 0.95 mm.

Operating temperature range is -55°C to 125°C, making it suitable for a wide range of environments. The component is RoHS compliant, REACH conform, and halogen-free, and has an MSL of 1. Storage conditions recommend keeping the part below 40 °C and 75% relative humidity.

This ferrite bead is intended for general electronic equipment and is not authorized for use in applications where failure could cause severe personal injury or death without a specific agreement.
