Procurement Notes

Verify the manufacturer designation as Taiyo Yuden or All Sensors, as both entities appear in public records for this part number. Confirm RoHS compliance status and lead-free certification prior to procurement. Ensure the specific package type matches the required surface-mount footprint for the target application circuit design.

Selection Notes

Select this component when filtering high-frequency noise on multi-line signal paths requiring 700 ohms impedance at 60 MHz. The 500 mA current rating suits low-power data lines. Verify that the 50 V voltage rating aligns with the system's operational limits. Consider the 3-line configuration if multiple signal pairs require simultaneous common mode suppression.

Part Context

This component belongs to the BU series of SMD common mode choke coils from Taiyo Yuden. These coils are engineered for suppressing electromagnetic interference in compact electronic devices. The series typically offers various impedance and current ratings to accommodate different signal integrity requirements in portable and office equipment.
