WLBD3225K2U900PP

Overview

The WLBD3225K2U900PP is a shielded ferrite chip bead manufactured by Walsin Technology Corporation. It features a 1210 (3225 metric) surface-mount package with dimensions of 3.2 mm length, 2.5 mm width, and 1.3 mm height. The component provides an impedance of 90 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 300 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

• Shielded construction minimizes electromagnetic interference radiation
• Flexible soft terminals enhance solder joint reliability during thermal cycling
• Single-channel design integrates one element for compact circuit layouts

Applications

• High-speed data line noise suppression in portable devices
• Power supply filtering in network infrastructure equipment
• Signal integrity management in smartphone circuits

Procurement Notes

Verify the specific ordering suffix K2 against the manufacturer's latest datasheet to confirm terminal type and packaging configuration. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a 1210 footprint is required for high-current applications up to 800 mA. The 90 Ohm impedance at 100 MHz suits broadband noise suppression needs. Consider the shielded design for environments requiring reduced EMI radiation. Verify that the 300 mOhm DC resistance meets power loss constraints in the specific circuit path.
