Z0603C391APMST

Overview

The KEMET Z0603C391APMST is a surface-mount ferrite bead designed for power line noise suppression in the 0603 (1608 metric) package. It exhibits an impedance of 390 ohms at 100 MHz and supports a maximum current rating of 1 A. The component features a low DC resistance of 0.14 ohms and operates within a temperature range of -55°C to +85°C. Packaged in tape and reel format, it belongs to the Z-PMS series and complies with RoHS3 standards.

Feature Summary

• Provides high impedance noise attenuation on power lines
• Compact 0603 footprint for space-constrained designs
• Low DC resistance minimizes voltage drop
• Robust construction for automotive-grade reliability

Applications

• Power supply input filtering
• Noise suppression in automotive electronics
• High-frequency interference mitigation in compact modules

Procurement Notes

Verify the specific suffix 'PMST' against the manufacturer's latest datasheet to confirm impedance tolerance and terminal plating specifications. Ensure the selected packaging quantity aligns with production requirements, as standard reels typically contain 4,000 units. Confirm compliance with current environmental directives such as RoHS3 before finalizing procurement orders.

Selection Notes

Select this component when a 390-ohm impedance at 100 MHz is required for power line filtering. The 1 A current rating suits moderate power applications. Consider the 0.14 ohm DC resistance impact on circuit efficiency. The 0603 size is optimal for dense PCB layouts where larger ferrites cannot fit.

Part Context
