BBPY00201209471Y00

Overview

The BBPY00201209471Y00 is a surface-mount ferrite bead manufactured by Pulse Electronics Corporation, designed for electromagnetic interference (EMI) suppression in electronic circuits. This component features a 0805 (2012 Metric) package with physical dimensions of 2mm length and 1.2mm width. It provides an impedance of 470 Ohms at 100 MHz with a tolerance of ±25%. The device supports a maximum DC current rating of 2A and exhibits a maximum DC resistance of 0.1 ohms.

Feature Summary

• Provides effective high-frequency noise suppression through EMI filtering capabilities
• Utilizes a compact 0805 surface-mount footprint for space-constrained designs
• Supports continuous DC currents up to 2A with low series resistance

Applications

• High-speed data line filtering
• Power supply output decoupling
• General-purpose EMI suppression in consumer electronics

Procurement Notes

Verify the specific manufacturer part number against official Pulse Electronics documentation to ensure authenticity. Confirm that the requested component matches the 0805 package size and 470 Ohm impedance specifications required for your circuit design. Cross-reference technical parameters such as DC resistance and current ratings with the latest datasheet to avoid compatibility issues during integration.

Selection Notes

Select this component when a 470 Ohm impedance at 100 MHz is required for noise attenuation. Ensure the circuit operates within the 2A DC current limit to prevent saturation or excessive heating. The 0.1 ohm maximum DC resistance makes it suitable for power lines where minimal voltage drop is critical. Verify that the 0805 package fits the available PCB real estate.

Part Context

This ferrite bead belongs to Pulse Electronics' passive component portfolio, specifically engineered for signal integrity and power line conditioning. Ferrite beads function as frequency-dependent resistors, dissipating high-frequency energy as heat while allowing DC and low-frequency signals to pass unaffected. They are essential for meeting regulatory EMC standards in modern electronic devices.
