Z1806C900BPWST

Overview

The KEMET Z1806C900BPWST is a power line ferrite chip bead designed for noise suppression in electronic circuits. It features an 1806 surface-mount package and provides a nominal impedance of 90 Ohms at its rated frequency. The component supports a maximum current rating of 4 Amperes with a low DC resistance of 14 milliohms, ensuring minimal signal loss while effectively attenuating electromagnetic interference on power lines.

Feature Summary

• Provides effective filtering and EMI suppression for both radiant and conductive noise on power lines
• Engineered for high-current applications with a 4A rating and low DC resistance to maintain circuit efficiency
• Utilizes a compact 1806 surface-mount footprint suitable for automated assembly processes

Applications

• Power line noise suppression in automotive electronics
• EMI filtering for industrial control systems
• Noise attenuation in consumer power supply circuits

Procurement Notes

Verify the specific impedance tolerance and current derating curves against your application requirements before procurement. Confirm that the 1806 package dimensions align with your PCB layout constraints. Ensure the supplier provides authentic components from authorized channels to guarantee performance consistency and reliability in final assemblies.

Selection Notes

Select this component when high current handling capability is required alongside significant noise reduction. The low DC resistance minimizes voltage drop across the component, making it suitable for sensitive power rails. Consider the thermal management capabilities of the 1806 package if operating near the maximum current rating in enclosed environments.

Part Context

This ferrite bead belongs to KEMET's Z-PWS series, which specializes in power line noise suppression. The series is characterized by robust construction and high saturation currents, addressing the growing need for reliable EMI control in modern electronic devices where space and current capacity are critical design factors.

Replacement Considerations

Check datasheets for equivalent parts offering similar 90-ohm impedance and 4A current ratings. Verify package compatibility and thermal characteristics to ensure seamless integration without redesigning the PCB layout or compromising noise suppression performance.
