WLBD2012HCU301TH

Overview

The WLBD2012HCU301TH is a fixed ferrite bead component manufactured by Walsin Technology Corporation. It operates as a single-line power line filter with an impedance of 300 Ohms at 100 MHz. The device features a maximum DC resistance of 90mOhm and supports a current rating of 2A. It utilizes a 2012 (0805 metric) surface mount package, measuring 2.0 mm in length and 1.2 mm in width.

Feature Summary

• Provides effective noise suppression for power lines through high impedance characteristics at target frequencies
• Engineered for compact surface mount integration within space-constrained electronic designs
• Constructed to handle specified current loads while maintaining low direct current resistance

Applications

• Power line filtering in portable electronic devices
• Noise suppression circuits in consumer electronics
• Signal integrity management in embedded systems

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official datasheet before procurement. Confirm that the 2012 package dimensions align with the printed circuit board layout constraints. Ensure compliance with relevant environmental standards such as RoHS if required by the final product specifications.

Selection Notes

Select this component when a low-profile ferrite bead is needed for power rail decoupling. The 300 Ohm impedance at 100 MHz targets common switching noise frequencies. Consider the 90mOhm DC resistance impact on voltage drop relative to the 2A current capacity during design validation.

Part Context

This ferrite bead belongs to Walsin's chip bead series designed for electromagnetic interference suppression. The 2012HC designation indicates a specific height profile within the 0805 footprint family, optimized for automated assembly processes in modern manufacturing environments.

Replacement Considerations

Cross-reference with other 2012 package ferrite beads offering 300 Ohms impedance at 100 MHz. Verify equivalent current ratings and DC resistance values to ensure functional compatibility without modifying the existing circuit design.
