Z0805C101APMST

Overview

The KEMET Z0805C101APMST is a surface-mount ferrite chip bead designed for electromagnetic interference suppression in power lines. It features an 0805 (2012 metric) package with a nominal impedance of 100 Ohms at 100 MHz. The component supports a maximum DC current of 2.5 A and maintains a low maximum DC resistance of 40 mOhms. It operates within a temperature range of -55°C to +85°C and belongs to the Z-PMS series.

Feature Summary

• Provides signal integrity protection through high-frequency noise attenuation on power lines
• Engineered for compact surface-mount integration using standard 0805 footprints
• Capable of handling continuous DC currents up to 2.5 Amperes without saturation

Applications

• Power line filtering in portable electronic devices
• Noise suppression in automotive infotainment systems
• EMI mitigation in industrial control circuitry

Procurement Notes

Verify the specific suffix 'PMST' against the manufacturer's latest datasheet to confirm impedance tolerance and termination specifications. Ensure the selected variant matches the required 100 Ohm @ 100 MHz characteristic for the target application frequency. Confirm RoHS compliance status if restricted substances are mandated by the end product regulations.

Selection Notes

Select this component when a low-profile, high-current ferrite bead is required for power rail decoupling. The 0805 case size offers a balance between current handling capacity and board space efficiency. Consider the 40 mOhm DC resistance limit to ensure minimal voltage drop across the component under full load conditions.

Part Context

This part belongs to KEMET's Z-PMS series of ferrite chip beads, which are specialized for power line applications. Unlike general-purpose beads, this series is optimized for higher current ratings while maintaining effective high-frequency impedance characteristics suitable for modern compact electronics.

Replacement Considerations

Cross-reference with other 0805 ferrite beads offering 100 Ohms @ 100 MHz and >2.5A current rating. Verify that substitute parts maintain compatible physical dimensions and thermal performance profiles.
