Overview
The Taiyo Yuden BK1608HW681-T is a multilayer ferrite bead designed for surface-mount technology in the 0603 (1608 metric) package. It provides an impedance of 680 ohms at a test frequency of 100 MHz with a maximum DC current rating of 250 mA and a maximum DC resistance of 700 milliohms. The component operates within a temperature range of -55°C to +125°C, featuring a compact footprint of 1.60 mm length by 0.80 mm width.
Feature Summary
- Multilayer chip construction for high-frequency noise suppression
- Compact 0603 surface-mount form factor
- High impedance characteristics at 100 MHz
Applications
- General electronic equipment including AV devices and office automation
- Information and communication equipment such as mobile phones and personal computers
- Automotive electronic systems
- Telecommunications infrastructure
- Medical devices classified under GHTF A-C and Japan I-III categories
Procurement Notes
Verify the specific datasheet version and RoHS compliance status before integration. Confirm that the 0603 package dimensions align with your PCB footprint design. Ensure the 250 mA current rating meets the circuit requirements to prevent saturation. Check for any recent product change notifications or end-of-life notices from the manufacturer.
Selection Notes
Select this component when high attenuation is required at 100 MHz within a limited board space. The 0603 size suits dense layouts where larger packages are unsuitable. Verify that the 700 milliohm DC resistance does not cause excessive voltage drop in the power line. Consider the -55°C to +125°C operating range for environmental suitability.
Part Context
This part belongs to the Taiyo Yuden BK series of multilayer ferrite beads. These components are engineered for electromagnetic interference suppression in digital circuits. The BK series offers various impedance values and current ratings across standard package sizes to support diverse EMC filtering needs in consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official distributor databases for cross-references based on impedance, current rating, and package compatibility.
