WLBD2012K2U102TP

Overview

The WLBD2012K2U102TP is a ferrite chip bead manufactured by Walsin Technology Corporation, designed for surface-mount applications in the 0805 (2012 metric) package. It provides an impedance of 1000 Ohms with a tolerance of +/-25% at a test frequency of 100 MHz. The component supports a maximum DC current of 600 mA and features a maximum DC resistance of 300 mOhms. It operates within a temperature range of -55°C to +125°C and has physical dimensions of 2.0 mm length, 1.25 mm width, and 1.2 mm height.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm terminal plating and packaging specifications. Ensure the selected reel quantity aligns with production requirements. Confirm RoHS compliance status directly with the supplier documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when a compact 0805 footprint is required for noise attenuation on lines carrying up to 600 mA. The 1 kOhm impedance value targets specific frequency bands around 100 MHz. Evaluate the low DC resistance to ensure minimal voltage drop impact on the circuit performance under load conditions.
