WLBD1005K2U600TP

Overview

The WLBD1005K2U600TP is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 60 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 350 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 electromagnetic interference suppression through high-impedance characteristics at specific frequencies
• Utilizes a shielded design to contain magnetic fields and reduce external noise coupling
• Features flexible soft terminals to enhance solder joint reliability during thermal cycling

Applications

• High-speed data line filtering in portable electronic devices
• Power supply noise suppression in compact circuit boards
• Signal integrity management in mobile communication modules

Procurement Notes

Verify the exact suffix against official Walsin documentation to confirm terminal type and packaging specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and lead times prior to ordering.

Selection Notes

Select this component when space constraints require a 0402 footprint with moderate current handling capabilities. The 60 Ohm impedance at 100 MHz makes it suitable for suppressing noise in digital signal lines. Consider the 300 mA current rating to ensure the component does not saturate under normal operating conditions. Verify compatibility with standard reflow soldering profiles for thin-film or ferrite materials.

Part Context

This ferrite bead belongs to Walsin's WLBD series of passive components designed for surface-mount technology. The series offers various impedance values and package sizes to address different EMI suppression needs in modern electronics. The 1005 metric size balances component density with electrical performance, fitting into densely populated PCB layouts common in consumer electronics.

Replacement Considerations

Check for direct substitutes from Walsin such as WLBD1005K1U600TB or WLBD1005HCU600TB if terminal flexibility or housing material differs. Evaluate alternative manufacturers like Murata or TDK for equivalent 0402 ferrite beads with matching 60 Ohm impedance and 300 mA ratings. Ensure pinout and mechanical dimensions are identical before substitution.
