WLBD2012K2U301TP

Overview

The WLBD2012K2U301TP is a ferrite bead manufactured by Walsin Technology Corporation, designed for electromagnetic interference (EMI) suppression in surface mount applications. It features a 0805 (2012 Metric) package size and provides an impedance of 300 Ohms at 100 MHz. The component supports a maximum current rating of 500mA with a low DC resistance of 200mOhm. It is RoHS compliant and suitable for high-frequency noise filtering in compact electronic circuits.

Feature Summary

• Provides effective EMI suppression through high impedance characteristics at target frequencies
• Compact 0805 surface mount footprint enables space-efficient PCB layouts
• Low DC resistance minimizes power loss while maintaining signal integrity

Applications

• High-speed data line filtering
• Power supply noise suppression
• Clock signal conditioning

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against your circuit design before procurement. Ensure the 0805 package dimensions align with your PCB land pattern. Confirm RoHS compliance status if required by your manufacturing standards. Check for any lead time variations as these may affect production schedules.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for noise filtering. Consider the 500mA current rating to ensure it meets the operational load without saturation. The 200mOhm DC resistance is critical for minimizing voltage drop in sensitive power lines. Evaluate the 0805 package size against available board space constraints.

Part Context

This ferrite bead belongs to Walsin's chip ferrite bead series, which are passive components used primarily for EMI/RFI suppression. These components are essential in modern electronics for maintaining signal purity and preventing interference between different circuit blocks. The 0805 form factor is widely adopted in consumer and industrial electronics for its balance of performance and size.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Verify compatibility with equivalent ferrite beads from other manufacturers based on impedance, current rating, and package dimensions.
