Procurement Notes

Verify the exact suffix against official manufacturer documentation to confirm terminal type and packaging specifications. Ensure the requested part matches the required impedance and current ratings for the target application. Confirm RoHS compliance status and lead-free certification requirements prior to ordering. Cross-reference the datasheet version to validate testing frequency and tolerance parameters.

Selection Notes

Select this component when space constraints require a 0402 footprint for EMI suppression. Evaluate the 300 mA current rating against the circuit's operational load to prevent saturation. Consider the 240 Ohm impedance profile for effective attenuation at the intended noise frequency. Verify compatibility with automated pick-and-place equipment due to the small package size.

Part Context

This ferrite bead belongs to Walsin's WLBD series of passive components designed for surface mount technology. The series offers various impedance values and current ratings within standardized metric packages.
