BK1608HM121-T

Overview

The BK1608HM121-T is a single-line ferrite bead from the Taiyo Yuden BK series, housed in a 0603 (1608 metric) surface-mount package. It exhibits an impedance of 120 Ohms at 100 MHz and supports a maximum rated current of 350 mA. The component features a maximum DC resistance of 200 milliohms and operates within a temperature range of -55°C to 125°C. This device is designed for electromagnetic interference suppression in compact electronic circuits.

Feature Summary

• Provides high-impedance attenuation for high-frequency noise signals
• Supports direct integration into surface-mount assembly lines
• Maintains stable electrical characteristics across wide industrial temperature ranges

Applications

• Electromagnetic interference filtering in portable communication devices
• Noise suppression on power supply lines for integrated circuits
• Signal integrity management in high-speed digital data buses

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinuation status. Confirm that replacement parts meet identical impedance and current ratings. Check for RoHS compliance documentation if required by specific regulatory standards. Ensure storage conditions prevent moisture damage prior to soldering.

Selection Notes

Select this component when space constraints require a 0603 footprint with moderate current handling capabilities. Evaluate thermal performance requirements against the specified operating temperature range. Compare alternative ferrite beads based on impedance frequency profiles and DC resistance limits to ensure circuit compatibility.

Part Context

This part belongs to the BK series of multilayer chip bead inductors manufactured by Taiyo Yuden. The series utilizes proprietary ceramic materials to achieve consistent magnetic properties. These components are engineered for mass production in consumer electronics and industrial equipment requiring reliable EMI suppression.

Replacement Considerations

Direct substitutes include Bourns MG1608-121Y and MH1608-121Y. Verify that these alternatives match the 120 Ohm impedance at 100 MHz and 350 mA current rating before implementation.
