Z0603C470BPWZT

Overview

The KEMET Z0603C470BPWZT is a surface-mount ferrite chip bead designed for electromagnetic interference suppression. It features a 0603 (1608 metric) case size with standard SMD terminations. The component provides an impedance of 47 ohms at the specified test frequency and supports a maximum DC current of 3.5 amperes. It exhibits a maximum DC resistance of 20 milliohms and maintains a tolerance of 25 percent. The device operates within a temperature range from -40 degrees Celsius to +125 degrees Celsius.

Feature Summary

• Provides effective high-frequency noise attenuation through ferrite material properties
• Supports high continuous current loads up to 3.5 amperes without saturation
• Utilizes a compact 0603 surface-mount footprint for space-constrained designs

Applications

• Power line filtering in automotive electronic modules
• Noise suppression on data buses in industrial control systems
• EMI mitigation in consumer electronics power supplies

Procurement Notes

Verify the specific impedance value against the official datasheet, as public listings may vary between 47 ohms and other values like 20.7 ohms depending on the exact revision or test frequency definition. Confirm the lifecycle status, as some sources indicate this part number may be obsolete or end-of-life. Ensure the selected variant matches the required DC current rating and physical dimensions for your PCB layout.

Selection Notes

Select this component when a low-impedance path is needed for DC while attenuating high-frequency noise. The 0603 package suits applications with limited board space. Consider the 3.5A current rating to ensure the component does not overheat under normal operating conditions. Verify that the 25% tolerance meets the circuit's noise suppression requirements.

Part Context

This ferrite bead belongs to KEMET's Z-series of passive components, specifically engineered for EMI suppression in surface-mount applications. The series offers various impedance and current ratings within standardized case sizes to facilitate design flexibility across different electronic industries.
