Overview
The PE-0805PFB301ST is a surface-mount ferrite bead designed for power line EMI suppression. It features a single-line configuration in an 0805 (2012 metric) package with dimensions of 0.079 inches length by 0.049 inches width and a maximum height of 0.041 inches (1.05mm). The component provides an impedance of 300 Ohms at 100 MHz and has a maximum DC resistance of 150 milliohms. It supports a rated current of 800mA and operates within a temperature range of -40°C to 105°C. The part is currently obsolete.
Feature Summary
- Provides effective electromagnetic interference suppression on power lines through high impedance characteristics at target frequencies.
Applications
- Power line filtering in electronic circuits
- EMI suppression for sensitive power rails
Procurement Notes
This component is officially listed as obsolete by the manufacturer. Verify availability through secondary distributors or consider end-of-life management strategies. Ensure compatibility with existing PCB footprints if utilizing remaining stock, as no new production is anticipated.
Selection Notes
Select this component only for legacy designs requiring specific 300 Ohm impedance at 100 MHz on power lines. Confirm that the 800mA current rating and 150 milliohm DCR meet circuit requirements. Due to its obsolete status, alternative sourcing or redesign may be necessary for new productions.
Part Context
Part of Pulse Electronics' FB series ferrite beads, specifically tailored for power line applications. The 0805 package size allows for compact surface-mount integration. This model represents a specialized solution for noise attenuation in power distribution networks where space constraints and specific impedance profiles are critical design factors.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Designers should consult official replacement guides or contact the manufacturer for qualified alternatives suitable for power line EMI suppression in the 0805 package.
