WLBD3216K2U122PP

Overview

The WLBD3216K2U122PP is a shielded 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 1200 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 400 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Flexible soft terminals accommodate board flexing during assembly
• Single-channel design for straightforward circuit integration

Applications

• High-frequency noise suppression in signal lines
• Power supply filtering for low-current circuits
• EMI reduction in portable electronic devices

Procurement Notes

Verify the specific suffix K2U against official Walsin documentation to confirm impedance characteristics and material composition. Ensure the ordering quantity aligns with standard reel or cut-tape configurations provided by distributors. Cross-reference the manufacturer part number with authorized channel listings to guarantee authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when high impedance at 100 MHz is required for noise attenuation. The 500 mA current rating suits applications with moderate power demands. Verify that the 1206 footprint fits the PCB layout constraints. Confirm thermal stability requirements fall within the specified -55°C to +125°C operational range for the target environment.
