WLBD1608HCU331TL

Overview

The WLBD1608HCU331TL is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 330 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current of 1.7 A and has a maximum DC resistance of 80 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective EMI suppression for high-frequency noise attenuation in power lines
• Features shielded construction to minimize electromagnetic interference
• Utilizes flexible soft terminals for reliable surface-mount soldering

Applications

• Power line filtering in electronic circuits
• EMI suppression in high-frequency applications
• Signal integrity management in compact devices

Procurement Notes

Verify the specific impedance value of 330 Ohms at 100 MHz against design requirements. Confirm the 1.7 A current rating and 80 mOhms DC resistance are sufficient for the target application. Ensure the 0603 package footprint matches the PCB layout. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a 330 Ohm impedance is required for noise suppression in space-constrained designs. The 0603 package allows for dense board layouts. Consider the 1.7 A current handling capability to ensure the bead does not saturate or overheat under normal operating conditions. Verify thermal performance within the specified -55°C to +125°C range.

Part Context

This part belongs to the WLBD series of ferrite beads from Walsin Technology Corporation. The series offers various impedance values in standard SMD packages. The WLBD1608HCU331TL specifically targets applications requiring moderate impedance in a compact form factor. It is designed for general-purpose EMI suppression in consumer and industrial electronics.

Replacement Considerations

Compatible substitutes include other 330 Ohm ferrite beads in the 0603 package, such as the WLBD1005HCU331TL if size reduction is acceptable. Verify that alternative parts meet the same 1.7 A current rating and 80 mOhms DC resistance specifications to maintain circuit performance.
