• AEC-Q200 qualified for automotive electronic applications
• Compact 0402 footprint suitable for space-constrained PCB layouts

Chip Ferrite Bead Applications

• Automotive infotainment system power filtering
• Industrial equipment signal integrity protection
• Medical device EMI suppression circuits

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'HM' against the official datasheet to confirm the operating temperature range and current rating, as variations exist within the BKP series. Confirm end-of-life status and lead times with authorized distributors, as availability may be restricted. Ensure RoHS compliance documentation matches the required regulatory standards for the target market.

Chip Ferrite Bead Selection Notes

Select this component when a compact 0402 ferrite bead is required for automotive-grade applications demanding 1.1 A current handling. The 120 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. Compare against the BKP1005HS121-TV if a wider operating temperature range up to 125°C is necessary, noting that the HS variant typically supports higher current ratings.

Chip Ferrite Bead Part Context

This part belongs to the BKP series of multilayer chip beads from Taiyo Yuden, specifically engineered for automotive and industrial environments. The series utilizes proprietary materials to achieve high saturation currents while maintaining low DC resistance. The HM designation indicates a specific thermal and electrical characteristic set distinct from other suffixes like HS or HW within the same physical package size.
