WLBD4532HCU120PH

Overview

The WLBD4532HCU120PH is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It features an impedance of 12 Ohms measured at a test frequency of 100 MHz with a tolerance of plus or minus 25 percent. The component utilizes a surface mount termination style and is housed in an 1812 package, corresponding to the 4532 metric dimension standard. Its physical dimensions are specified as 4.5 millimeters in length, 3.2 millimeters in width, and 1.5 millimeters in height. The device operates within a temperature range from negative 55 degrees Celsius to positive 125 degrees Celsius.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at specific frequencies
• Designed for surface mount assembly on printed circuit boards
• Constructed with shielded elements to manage noise effectively

Applications

• Power line filtering in electronic circuits
• Signal integrity management in data lines
• Noise reduction in RF applications

Procurement Notes

Verify the exact impedance value of 12 Ohms at 100 MHz against design requirements. Confirm the 1812 package dimensions match the PCB footprint. Ensure the operating temperature range of negative 55 to 125 degrees Celsius suits the environmental conditions. Check RoHS compliance status if required by regulatory standards. Validate the single-channel configuration meets the circuit topology needs.

Selection Notes

Select this component when a low impedance value of 12 Ohms is required for noise suppression rather than high attenuation. The 1812 package offers a balance between current handling capability and board space efficiency. Consider the wide operating temperature range for applications subject to thermal variation. The shielded construction helps prevent magnetic field interference with nearby components. Verify that the surface mount termination style aligns with the manufacturing process capabilities.
