Z1806C720APWST

Overview

The KEMET Z1806C720APWST is a surface-mount power line ferrite bead designed for EMI suppression. It features an 1806 package with a nominal impedance of 72 Ohms at 100 MHz and a maximum DC resistance of 7 milliohms. The component supports a rated current of 6 Amperes and operates within a temperature range of -40°C to +125°C. It complies with RoHS standards and is part of the Z-PWS series, intended for filtering radiant and conductive noise on power lines.

Feature Summary

• Provides high-frequency noise suppression for power lines
• Low DC resistance minimizes voltage drop in high-current applications
• Supports high continuous current ratings up to 6 Amperes
• RoHS compliant construction for environmental safety

Applications

• EMI filtering on power supply input lines
• Suppression of conductive noise in electronic circuits
• Filtering radiant noise in power distribution networks

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official datasheet before ordering. Confirm that the 1806 package dimensions align with your PCB footprint design. Ensure the supplier provides documentation confirming RoHS compliance and material composition as specified by KEMET.

Selection Notes

Select this component when low insertion loss and high current handling are critical. The 72 Ohm impedance targets specific noise frequencies around 100 MHz. Consider the 1806 size for space-constrained boards requiring robust power line filtering without significant thermal impact due to low resistance.

Part Context

This ferrite bead belongs to the KEMET Z-PWS series, which specializes in power line noise suppression. These components are engineered to handle higher currents compared to standard signal line beads, making them suitable for direct integration into power paths where both noise reduction and electrical efficiency are required.

Replacement Considerations

Consult official KEMET substitution guides for verified alternatives. Ensure any substitute matches the 1806 package, 72 Ohm impedance, 6A current rating, and 7 milliohm resistance specifications.
