Overview
The BK20104L470-T is a multilayer chip bead inductor array manufactured by Taiyo Yuden. It features an 0804 (2010 metric) surface-mount package with four independent ferrite beads. The component provides an impedance of 47 Ohms at 100 MHz and supports a maximum current of 100 mA. Its DC resistance is specified at 400 mOhms, and it utilizes an eight-pad configuration for PCB mounting.
Feature Summary
- Integrates four independent ferrite beads within a compact surface-mount footprint
- Provides high-frequency noise suppression characteristics suitable for signal lines
- Utilizes a multi-pad terminal design to enhance thermal dissipation and mechanical stability
Applications
- High-speed data line filtering in portable electronic devices
- Noise suppression for USB and communication interfaces
- EMI reduction in compact consumer electronics assemblies
Procurement Notes
Verify the specific impedance tolerance and current rating against the latest manufacturer datasheet before integration. Confirm that the eight-pad footprint matches the target PCB layout. Ensure compatibility with standard reflow soldering profiles for multilayer ceramic components to maintain electrical integrity.
Selection Notes
Select this component when space constraints require multiple filter channels in a single package. The 0804 size offers a balance between footprint area and performance. Consider the 100 mA current limit for circuit design. The four-channel architecture simplifies routing compared to discrete components.
Part Context
This part belongs to the BK array series of multilayer chip bead inductors from Taiyo Yuden. These components are designed for applications requiring compact noise suppression solutions. The series typically includes various channel counts and impedance values to suit different circuit requirements.
Replacement Considerations
Check for direct substitutes such as the BK32164M102-T or other BK series variants from Taiyo Yuden. Verify that alternative parts match the 0804 footprint and four-channel configuration. Ensure equivalent impedance and current ratings are maintained.
