WLBD1005K2U200TP

Overview

The WLBD1005K2U200TP is a single-element ferrite chip bead manufactured by Walsin Technology Corporation. It features a 0402 (1005 metric) surface mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 20 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 200 mOhms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible SMD/SMT terminals.

Feature Summary

• Provides EMI suppression through high-frequency impedance characteristics in a compact shielded form factor.

Applications

• High-frequency circuit noise filtering
• Signal line interference suppression
• Power supply rail decoupling

Procurement Notes

Verify the specific suffix K2U against the manufacturer datasheet to confirm impedance and current ratings match design requirements. Ensure the 0402 footprint aligns with PCB silkscreen and paste mask specifications. Confirm RoHS compliance status via official documentation before finalizing procurement orders for regulatory adherence.

Selection Notes

Select this component when low impedance values are required for minimal signal attenuation while maintaining noise suppression capabilities. The 300 mA current rating suits moderate power applications. Consider the 200 mOhm DC resistance impact on voltage drop. The wide operating temperature range ensures reliability across diverse environmental conditions without derating.

Part Context

This part belongs to the WLBD series of ferrite beads from Walsin Technology Corporation. The series offers various impedance options in standard metric packages. The WLBD1005K2U200TP specifically targets applications requiring precise low-impedance filtering in space-constrained designs.

Replacement Considerations
