Overview
The WLBD2012K2U300TP is a ferrite chip bead manufactured by Walsin Technology Corporation, designed for surface-mount applications. It features a 2012 (0805 metric) package with dimensions of 2.0 mm length, 1.2 mm width, and 1.2 mm height. The component provides an impedance of 30 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 600 mA and has a maximum DC resistance of 80 mOhms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible SMD/SMT terminations.
Feature Summary
- Provides effective high-frequency noise suppression through ferrite material properties
- Features shielded construction to minimize electromagnetic interference
- Utilizes flexible soft terminations to enhance solder joint reliability
Applications
- High-frequency noise filtering in electronic circuits
- Signal integrity enhancement in data lines
- Power supply line decoupling
Procurement Notes
Verify the specific part number WLBD2012K2U300TP against official Walsin documentation to confirm impedance values and package dimensions. Ensure compatibility with surface-mount assembly processes. Check for RoHS compliance status as indicated in manufacturer datasheets. Confirm availability through authorized distributors or direct manufacturer channels.
Selection Notes
Select this component when a 30 Ohm impedance at 100 MHz is required for noise attenuation in 2012 packages. Consider the 600 mA current rating for power line applications. Evaluate the thermal operating range for environmental suitability. Compare with similar ferrite beads if higher current capacity or different impedance characteristics are needed.
Part Context
This ferrite bead belongs to Walsin's WLBD series of passive components. The series includes various impedance values and package sizes for EMI suppression. The WLBD2012K2U300TP specifically addresses needs for moderate current handling in compact surface-mount designs.
Replacement Considerations
Publicly confirmed substitute part numbers for WLBD2012K2U300TP were not identified in available documentation. Verify electrical equivalence with other 30 Ohm 2012 ferrite beads from different manufacturers before substitution.
