BBFY00100505221YHN

Overview

The BBFY00100505221YHN is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It features an impedance of 270 ohms with a 25% tolerance and operates within a temperature range of -55°C to +125°C. The component supports a maximum DC current of 700 mA and has a maximum DC resistance of 280 mOhms. It utilizes SMD/SMT termination and is housed in a 0402 (1005 metric) package measuring 1 mm in length.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Multilayer ferrite technology for compact footprint integration
• High-temperature stability suitable for demanding environments

Applications

• Signal line filtering in portable electronics
• Power supply noise suppression in embedded systems
• EMI reduction in high-speed digital circuits

Procurement Notes

Verify the exact suffix against official Pulse Electronics documentation, as variations such as YHP or YHN may indicate specific packaging or tape-and-reel configurations. Confirm RoHS compliance status directly from the manufacturer datasheet before procurement. Ensure the ordering part number matches the required impedance and current ratings for your specific circuit design requirements.

Selection Notes

Select this component when a 0402 footprint is required with 270 ohms impedance at 100 MHz. The 700 mA current rating suits moderate power applications where low DCR is beneficial. Compare against BBSJ or BBNQ series variants if different current-to-impedance ratios are needed while maintaining the same physical dimensions and shielding characteristics.

Part Context

This part belongs to the BBFY series of shielded ferrite beads from Pulse Electronics. These components are designed for surface-mount assembly on printed circuit boards. The series offers various impedance and current combinations within standard industrial footprints, providing consistent EMI suppression performance across diverse electronic applications.

Replacement Considerations

Cross-reference with BBSJ00100505221Y00 or BBNQ00100505221Y00 for similar impedance but different current handling capabilities. Verify that substitute parts maintain the 0402 package size and shielded construction to ensure mechanical fit and electromagnetic performance compatibility.
