Overview
The BK1608HM681-T is a single-line multilayer chip ferrite bead from Taiyo Yuden, housed in a compact 0603 (1.60mm x 0.80mm) surface-mount package with a maximum height of 0.95mm. It provides an impedance of 680 ohms at a test frequency of 100 MHz and supports a rated current of 200 mA. The component features a maximum DC resistance of 700 milliohms and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides high impedance for effective electromagnetic interference suppression in signal lines
- Constructed using multilayer technology for reliable performance in harsh environments
- Designed for surface-mount assembly to facilitate automated manufacturing processes
Applications
- Electromagnetic compatibility filtering in electronic circuits
- Noise suppression for high-speed digital signal lines
- Power line filtering in automotive and industrial equipment
Procurement Notes
Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compliance with current RoHS standards and material specifications. Confirm that the 0603 footprint dimensions align with your PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when a 680-ohm impedance at 100 MHz is required for noise attenuation. Ensure the circuit current does not exceed the 200 mA rating to prevent saturation. Consider the low DC resistance characteristic for minimal signal loss in sensitive applications.
Part Context
This ferrite bead belongs to the BK series of multilayer chip bead inductors manufactured by Taiyo Yuden. The series is engineered for EMI suppression in consumer electronics, automotive systems, and industrial machinery, offering consistent electrical characteristics across various operating temperatures.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative components based on identical impedance curves, current ratings, and physical dimensions.
