ABPY00201209471Y00

Overview

The ABPY00201209471Y00 is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It features an 0805 (2012 metric) surface-mount package with dimensions of 2 mm length, 1.25 mm width, and 0.9 mm height. The component provides an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 2 A and has a maximum DC resistance of 100 mOhms. The operating temperature range spans from -40°C to +125°C.

Feature Summary

• Integrated shielding design to minimize electromagnetic interference radiation
• Multilayer construction for compact surface-mount integration
• High current handling capability suitable for power line filtering

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• High-speed digital signal line EMI reduction

Procurement Notes

Verify the specific impedance value and current rating against the latest official datasheet before procurement. Confirm that the 0805 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when high impedance at 100 MHz is required alongside significant DC current capacity. The shielded structure makes it appropriate for space-constrained designs where radiated emissions must be controlled. Compare the 100 mOhm DCR against voltage drop constraints in the circuit. Evaluate the 2 A rating against peak load currents to prevent saturation or excessive heating.

Part Context

This part belongs to the ABPY series of shielded ferrite beads from Pulse Electronics. The series is designed for applications requiring effective noise suppression in compact form factors. The 0805 package size balances performance with board space efficiency. It serves as a passive component for maintaining signal integrity in mixed-signal environments.

Replacement Considerations

Check for direct substitutes within the ABPY series with different impedance values if 470 Ohms is unavailable. Verify that any replacement maintains the 0805 footprint and 2 A current rating. Ensure the shielding characteristics of alternative parts provide comparable EMI performance.
