BBUP00321611221Y00

Overview

The BBUP00321611221Y00 is a shielded multilayer ferrite chip bead manufactured by Pulse Electronics. It features an SMD/SMT termination type within the BBUP series, housed in a 1206 (3216 metric) package measuring 3.2 mm in length. The component provides an impedance of 220 Ohms with a tolerance of 25% and supports a maximum DC current of 4.5 A. Its maximum DC resistance is 20 mOhms, ensuring low power loss during operation. The device operates reliably across a temperature range from -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Multilayer ferrite technology enables high current handling capability
• SMD/SMT termination facilitates automated surface mount assembly

Applications

• Power line filtering in portable electronic devices
• EMI suppression in automotive electronics systems
• Signal integrity protection in industrial control circuits

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 1206 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when high current capacity is required alongside effective noise suppression. The shielded design is suitable for dense layouts where crosstalk must be minimized. Compare the 220 Ohm impedance against circuit noise profiles to ensure adequate attenuation without affecting signal integrity. Consider the low DCR for efficiency-critical power paths.

Part Context

This component belongs to the BBUP series of shielded ferrite beads from Pulse Electronics. The series is designed for applications requiring robust EMI suppression in space-constrained environments. The 1206 package size offers a balance between current handling and board real estate. Similar parts in the series vary primarily in impedance and current ratings.

Replacement Considerations

Check for direct substitutes with identical 220 Ohm impedance and 4.5 A current rating. Verify that alternative components maintain the same shielded construction and 1206 package dimensions. Ensure thermal performance matches the original specifications.
