PE-0402HFB601ST

Overview

The PE-0402HFB601ST is a surface-mount ferrite chip bead from Pulse Electronics, designed for EMI noise suppression in high-speed circuits. It features a 0402 (1005 Metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 600 Ohms at its rated frequency. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 850 mOhm. The device operates within a temperature range of -40°C to +105°C.

Feature Summary

• Miniature 0402 footprint optimized for space-constrained PCB layouts
• High-frequency EMI noise filtering capability for signal integrity
• Robust thermal performance across extended industrial temperature ranges

Applications

• High-speed data line filtering
• Power supply output noise suppression
• Clock signal conditioning

Procurement Notes

Verify the specific ordering suffix and packaging configuration directly with the manufacturer or authorized distributors before purchase. Confirm that the requested quantity aligns with standard reel or cut-tape availability. Ensure the component meets all RoHS compliance requirements relevant to your target market. Cross-reference the full part number to avoid confusion with similar impedance variants in the FB series.

Selection Notes

Select this component when a compact form factor is required for filtering applications. The 600 Ohm impedance value suits specific noise profiles; verify against circuit simulation results. Consider the 300 mA current rating to ensure no saturation occurs under peak load conditions. The low DCR minimizes voltage drop in power lines. Evaluate the -40°C to +105°C range against environmental constraints.

Part Context

This part belongs to the Pulse Electronics FB series of ferrite beads. These components are passive devices used primarily for electromagnetic interference suppression. The 0402 size represents a standard small-outline package widely adopted in consumer electronics and telecommunications equipment for dense board designs.

Replacement Considerations

Check for direct substitutes such as the PE-0402FB601ST if impedance tolerance differences are acceptable. Verify mechanical compatibility with existing footprints. Ensure electrical parameters like impedance and current rating match or exceed original design specifications.
