WLBD3216K2U700PP

Overview

The WLBD3216K2U700PP is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It utilizes 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 70 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current of 800 mA and has a maximum DC resistance of 100 mOhms. The device operates within a temperature range of -55°C to +125°C and features flexible SMD/SMT terminations.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at specific frequencies.
• Features shielded construction to contain magnetic fields and reduce external noise coupling.
• Utilizes flexible soft terminations to enhance mechanical reliability during soldering and thermal cycling.

Applications

• High-speed data line filtering in portable electronic devices
• Power supply noise suppression in embedded systems
• Signal integrity management in communication modules

Procurement Notes

Verify the complete part number including suffixes to ensure correct impedance and tolerance specifications. Confirm RoHS compliance status via official manufacturer documentation prior to integration. Cross-reference datasheet parameters against design requirements for current handling and thermal performance. Ensure sourcing channels provide authentic components from authorized distributors to guarantee quality and traceability.

Selection Notes

Select this component when a 70 Ohm impedance at 100 MHz is required for EMI suppression in space-constrained designs. The 1206 footprint offers a balance between current handling capacity and board area efficiency. Consider the 800 mA rating for power lines or high-current signal paths. Evaluate the low DC resistance to minimize voltage drop and power loss in sensitive circuits.
