Overview
The WQBD1608HCU121TH is a ferrite chip bead manufactured by Walsin Technology Corporation, designed for surface-mount technology (SMD/SMT) applications. It features a 0603 (1608 metric) 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 2.5 A and has a maximum DC resistance of 70 mOhms. The device operates within a temperature range of -55°C to +125°C and includes flexible soft terminals.
Feature Summary
- Provides electromagnetic interference suppression through high-impedance characteristics at specific frequencies
- Utilizes shielded construction to contain magnetic fields and reduce external noise coupling
- Features flexible soft terminals to enhance solder joint reliability during thermal cycling
Applications
- Power supply circuits requiring noise filtering
- Battery charger systems
- Portable electronic devices
- Energy-efficient system designs
Procurement Notes
Verify the part number against official Walsin documentation to confirm specifications. Ensure compatibility with SMD/SMT assembly processes. Check RoHS compliance status via manufacturer datasheets. Confirm operating temperature ranges match application requirements. Validate impedance values at target frequencies before integration.
Selection Notes
Select this component based on required impedance at 100 MHz and current handling capacity. Consider the 0603 package size for space-constrained layouts. Evaluate thermal performance within the specified -55°C to +125°C range. Assess soldering compatibility with flexible terminal design. Compare DC resistance impact on circuit efficiency.
Part Context
Walsin Technology Corporation specializes in passive components, offering a comprehensive portfolio including ferrite beads. This product belongs to their ferrite chip bead series, designed for signal integrity and power line filtering. The WLBD and WQBD prefixes denote specific series variations within their ferrite component lineup.
Replacement Considerations
WLBD1608HCU121TH is a documented equivalent from the same manufacturer family. Verify pinout and electrical parameters match before substitution. Cross-reference package dimensions and terminal types for mechanical compatibility.
