PE-0805PFB331ST

Overview

The PE-0805PFB331ST is a surface-mount ferrite bead from the 0805PFB series by Pulse Electronics. It features a 330 Ohm impedance at 100 MHz, rated for a maximum current of 1.5 A with a DC resistance of 100 mΩ. The component utilizes a rectangular SMT package measuring 2.0 mm in length and 1.25 mm in width, operating within a temperature range of -40°C to +105°C.

Feature Summary

• Provides high impedance to suppress electromagnetic interference in high-speed signal lines
• Supports continuous currents up to 1.5 Amperes with low DC resistance
• Designed for compact surface-mount integration in space-constrained PCB layouts

Applications

• High-speed data line filtering
• Power supply noise suppression
• EMI/RFI mitigation in consumer electronics

Procurement Notes

Verify the specific impedance tolerance and current rating against the official datasheet before integration. Confirm that the 0805 footprint dimensions align with the target PCB design. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component when a 330 Ohm attenuation value is required for noise reduction without significant DC voltage drop. The 1.5 A rating suits moderate power applications. Consider the 100 mΩ DC resistance impact on circuit efficiency during initial design phases.

Part Context

This ferrite bead belongs to Pulse Electronics' 0805PFB series, designed for general-purpose EMI suppression. It complements other passive components like capacitors and inductors in filter networks. The series offers standardized footprints for easy replacement in existing designs requiring noise control.

Replacement Considerations

Substitute only with components sharing identical 330 Ohm impedance, 1.5 A current rating, and 0805 footprint. Verify thermal characteristics and impedance frequency response curves match the original specification to maintain circuit performance.
