WLBD3216HCU122PH

Overview

The WLBD3216HCU122PH is a single-element 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 1.3 mm height. The component provides an impedance of 1.2 kOhms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current of 1 A 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 soft terminals for SMD/SMT mounting.

Feature Summary

• Provides high impedance filtering for power lines in the 1206 surface-mount footprint
• Utilizes shielded construction to minimize electromagnetic interference
• Features flexible soft terminals designed to reduce mechanical stress on PCB pads

Applications

• Power line noise suppression in electronic circuits
• High-frequency signal attenuation in compact devices
• EMI/RFI filtering in portable electronics

Procurement Notes

Verify the specific manufacturer part number against official Walsin documentation to ensure compatibility with design requirements. Confirm that the 1206 package dimensions and terminal specifications match the target PCB layout. Check for RoHS compliance status through official datasheets or environmental reports provided by the manufacturer before finalizing procurement decisions.

Selection Notes

Select this component when a 1.2 kOhm impedance at 100 MHz is required for power line filtering in a 1206 package. Ensure the circuit current does not exceed 1 A to prevent saturation. Verify that the 200 mOhms DC resistance meets the voltage drop constraints of the application. Confirm that the operating temperature range covers the intended environmental conditions.
