Applications

• Signal line noise suppression
• High-speed data interface filtering
• RF circuit interference reduction

Procurement Notes

Verify the specific manufacturer datasheet for final electrical characteristics and mechanical dimensions before integration. Confirm RoHS compliance status and end-of-life notifications directly with KEMET or authorized distributors, as availability may vary by region and production batch.

Selection Notes

Select this component when a compact ferrite bead with 430 ohms impedance at 100 MHz is required for signal integrity management. Ensure the application current does not exceed 350 mA to prevent saturation. Consider the 0402 package size constraints and thermal operating limits during PCB layout planning.
