Overview
The WLBD1005HCU221TL is a single-element ferrite chip bead manufactured by Walsin Technology Corporation. It features an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. The component supports a maximum DC current of 1.4 A and has a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1 mm in length, 0.5 mm in width, and 0.5 mm in height, corresponding to the 0402 (1005 metric) package size.
Feature Summary
- Provides EMI suppression capabilities for high-frequency power line applications through ferrite material properties.
- Features flexible soft terminals designed to enhance solder joint reliability during surface mount assembly.
- Utilizes a shielded construction to contain electromagnetic interference effectively.
Applications
- EMI suppression in high-frequency power line circuits
- Signal integrity management in compact electronic devices
- Noise filtering in portable consumer electronics
Procurement Notes
Verify the specific suffix TL against official Walsin documentation to confirm reel packaging specifications. Ensure the impedance value of 220 Ohms matches the target noise frequency spectrum. Confirm RoHS compliance status directly from the manufacturer's datasheet before integration into regulated products.
Selection Notes
Select this component when space constraints require a 0402 footprint for ferrite beads. The 1.4 A current rating suits moderate power lines where low DC resistance is critical. Verify that the 220 Ohm impedance provides sufficient attenuation at the specific interference frequency of interest.
Part Context
This part belongs to the WLBD series of ferrite chip beads from Walsin Technology Corporation. The series offers various impedance values and package sizes to address different EMI suppression needs. The WLBD1005HCU221TL specifically targets applications requiring compact solutions with defined high-frequency noise characteristics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult Walsin technical support or authorized distributors for verified cross-references based on impedance and current requirements.
