Applications
- Automotive electronic circuit protection
- Electromagnetic interference (EMI) filtering in vehicle systems
- Signal line noise suppression in automotive modules
Procurement Notes
Verify the specific suffix 'TV' against official Taiyo Yuden documentation to confirm packaging details, as suffixes often denote reel specifications or tape-and-reel variations. Confirm end-of-life status and obsolescence notices via manufacturer product change notifications before finalizing procurement plans.
Selection Notes
Select this component when automotive-grade reliability and compact size are required for EMI suppression. Ensure the 500 mA current rating meets the circuit's operational requirements. Verify that the 120 Ohm impedance at 100 MHz aligns with the target noise frequencies. Check for RoHS compliance and AEC-Q200 qualification if mandated by the application standards.
Part Context
This part belongs to the BK series of multilayer chip bead inductors from Taiyo Yuden. The series is characterized by its use in high-reliability applications, particularly within the automotive sector. The BK1005 designation indicates the standard 0402 package size, while the HM suffix typically denotes specific material properties optimized for automotive performance.
