WLBD1005K2U102TP

Overview

The WLBD1005K2U102TP 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 1 kOhms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 1.5 Ohms. 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 single-line circuits
• Utilizes shielded construction to minimize electromagnetic interference
• Features flexible soft terminals designed to reduce mechanical stress on the substrate during soldering

Applications

• High-speed data line filtering
• Power supply noise suppression
• Clock signal conditioning

Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm packaging details and terminal specifications. Ensure the ordered quantity aligns with the factory reel size of 10,000 units or verify cut tape availability requirements. Confirm RoHS3 compliance status matches project environmental standards before finalizing procurement orders.

Selection Notes

Select this component when a 1 kOhm impedance value is required at 100 MHz for EMI suppression in compact designs. The 0402 footprint allows for dense PCB layouts. Verify that the circuit's DC current does not exceed 200 mA to prevent saturation. Consider the 1.5 Ohm DC resistance impact on voltage drop for low-voltage applications.

Part Context

This part belongs to the WLBD series of ferrite beads from Walsin Technology Corporation. The series offers various impedance values and current ratings in standard metric packages. The WLBD1005K2U102TP specifically targets applications requiring moderate current handling with high-frequency noise attenuation in space-constrained environments.

Replacement Considerations

Consult Walsin's official cross-reference documentation for verified substitutes. Generic equivalents may differ in impedance curves or current ratings. Do not assume functional interchangeability without verifying electrical parameters against the original datasheet.
