WLBD3225HCU102PH

Overview

The WLBD3225HCU102PH is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It utilizes 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 exhibits an impedance of 1 kOhms at a test frequency of 50 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 2 A and maintains a maximum DC resistance of 90 mOhms. The device operates within a temperature range of -55°C to +125°C and features flexible SMD/SMT terminations.

Feature Summary

• Provides high impedance attenuation for noise suppression in power line applications
• Features shielded construction to minimize electromagnetic interference
• Utilizes flexible soft terminations for enhanced reliability during soldering processes

Applications

• Power line filtering in electronic circuits
• Noise suppression in signal lines
• EMI reduction in portable devices

Procurement Notes

Verify the specific datasheet version provided by Walsin Technology Corporation before integration. Confirm that the 1210 package dimensions and terminal compatibility match your PCB layout requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the impedance characteristics at 50 MHz with your circuit design needs to validate performance expectations.

Selection Notes

Select this component when a 1 kOhm impedance at 50 MHz is required for noise control. The 2 A current rating suits moderate power applications. The 1210 footprint offers a balance between size and thermal handling. Verify that the 90 mOhm DCR aligns with your voltage drop constraints. Consider the -55°C to +125°C range for broad environmental adaptability.

Part Context

This ferrite bead belongs to the WLBD3225HC series from Walsin Technology Corporation. The series includes variants with different impedance values, such as the WLBD3225HCU600PH which offers 60 Ohms at 100 MHz. These components are designed for surface-mount technology and are commonly used in consumer electronics and industrial equipment for EMI suppression.

Replacement Considerations

Direct substitutes must match the 1210 package, 1 kOhm @ 50 MHz impedance, and 2 A current rating. Verify termination style and DCR limits. No specific alternative part numbers are confirmed in public documentation.
