WLBD1608HCU121TL

Overview

The WLBD1608HCU121TL 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 120 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 3 A and has a maximum DC resistance of 30 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 designed to minimize electromagnetic interference in compact circuits
• Flexible soft terminal technology ensures reliable soldering and mechanical stability
• Single-line configuration optimized for power line noise suppression

Applications

• Power line filtering in portable electronic devices
• EMI suppression in high-speed digital signal lines
• Noise reduction in automotive electronics systems

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the requested quantity matches available packaging formats such as cut tape or reel. Ensure that the component's thermal and current ratings align with the target application requirements to prevent performance degradation.

Selection Notes

Select this component when a low-profile 0603 footprint is required for space-constrained designs. The 120 Ohm impedance at 100 MHz makes it suitable for broadband noise attenuation. Consider the 3 A current rating to ensure adequate headroom for power delivery lines without excessive resistive heating or voltage drop.

Part Context

This part belongs to the WLBD series of shielded ferrite beads from Walsin Technology Corporation. The series offers various impedance values and current ratings within standard industry footprints. The WLBD1608HCU121TL specifically addresses the need for effective EMI suppression in small form-factor applications where traditional unshielded beads may cause radiation issues.

Replacement Considerations

Cross-reference with other 0603 ferrite beads offering 120 Ohms impedance and similar current handling capabilities. Verify pin compatibility and impedance curves to ensure equivalent noise suppression performance. Check for availability of alternative manufacturers if supply chain constraints exist.
