WLBD3216K2U202PP

Overview

The WLBD3216K2U202PP is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 2 kOhms at a test frequency of 30 MHz with a tolerance of ±25%. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 500 mOhms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible soft terminals for SMD/SMT mounting.

Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression in the specified frequency band.
• Features shielded construction to minimize external magnetic field interaction.
• Utilizes flexible soft terminals to enhance solder joint reliability during thermal cycling.

Applications

• High-frequency noise filtering in portable electronic devices
• Signal integrity management in computer peripheral interfaces
• EMI suppression in telecommunications equipment signal lines

Procurement Notes

Verify the specific suffix PP against official Walsin documentation to confirm packaging configuration and reel specifications. Ensure the ordered quantity aligns with the manufacturer's standard factory pack size of 3000 units or cut tape availability. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when circuit design requires significant impedance at 30 MHz while maintaining low DC resistance. The 200 mA current rating suits low-power signal lines rather than power delivery paths. The 1206 footprint offers a balance between current handling capability and board space efficiency compared to smaller packages.

Part Context

This ferrite bead belongs to Walsin's WLBD series of passive components designed for EMI/RFI suppression. The series includes various impedance values and current ratings within standardized metric footprints. These components are engineered for integration into compact consumer electronics and industrial control systems requiring reliable noise filtration.

Replacement Considerations

Cross-reference impedance curves and current ratings with alternative manufacturers such as Murata or TDK. Verify that substitute parts maintain compatibility with the 1206 footprint and meet the same thermal operating limits of -55°C to +125°C.
