WLBD1608K2U181TP

Overview

The WLBD1608K2U181TP 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 180 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current of 1.3 A 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

• Provides high impedance attenuation for noise suppression in high-frequency circuits
• Features shielded construction to minimize electromagnetic interference
• Utilizes flexible soft terminals to enhance solder joint reliability during reflow

Applications

• Noise suppression in portable electronic devices
• Signal integrity management in consumer electronics
• Power line filtering in compact circuit boards

Procurement Notes

Verify the specific impedance value and current rating against the official Walsin datasheet before integration. Confirm that the 0603 package footprint matches the PCB design. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check RoHS compliance status as indicated in the manufacturer documentation.

Selection Notes

Select this component when a 180 Ohm impedance is required at 100 MHz for noise control. The 1.3 A current rating suits applications with moderate power consumption. The 0603 size allows for dense board layouts. Compare DCR values if voltage drop across the bead is a critical design constraint.

Part Context

This ferrite bead belongs to Walsin's WLBD series of passive components designed for EMI suppression. The series offers various impedance levels and current ratings within standard industrial footprints. These components are engineered for use in modern electronics where space constraints and signal purity are primary design drivers.

Replacement Considerations

Cross-reference with other 0603 ferrite beads offering 180 Ohms impedance and similar current handling capabilities. Verify terminal compatibility and thermal characteristics before substitution.
