Z0805C331APMST

Overview

The KEMET Z0805C331APMST is a multilayer ferrite chip bead designed for power line noise suppression in the Z-PMS series. It features an 0805 (2012 metric) surface-mount package with dimensions of 2.0 mm length, 1.25 mm width, and 0.95 mm height. The component provides an impedance of 330 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1.5 A and has a maximum DC resistance (DCR) of 75 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation on power lines
• Compact 0805 surface-mount footprint suitable for space-constrained PCB layouts
• High current handling capability of 1.5 A with low DC resistance to minimize voltage drop

Applications

• Power line filtering in portable electronic devices
• Noise suppression in automotive electronics systems
• EMI reduction in industrial control equipment

Procurement Notes

Verify the specific suffix 'PMST' against the manufacturer's latest documentation to confirm packaging details and RoHS compliance status. Confirm availability as this part may be subject to end-of-life notices or limited stock conditions depending on the distributor. Ensure the selected supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when a 330 Ohm impedance at 100 MHz is required for power rail filtering. The 0805 package offers a balance between current capacity and board space. Compare the 75 mOhm DCR against circuit requirements to ensure acceptable power loss. Consider the Z-PMS series characteristics for thermal stability and mechanical robustness in demanding environments.

Part Context

This ferrite bead belongs to KEMET's Z-PMS series, which focuses on power line applications. The series utilizes multilayer technology to provide consistent performance across a wide temperature range. The 0805 case size is standard for general-purpose surface-mount designs, allowing compatibility with automated pick-and-place manufacturing processes commonly used in modern electronics assembly.
