FBU453215T-681Y-S

Chip Ferrite Bead Overview

The FBU453215T-681Y-S is a single-line ferrite bead from Cal-Chip Electronics, Inc., housed in an 1812 (4532 metric) surface-mount package. It provides an impedance of 680 Ohms at 100 MHz with a maximum DC resistance of 30 mOhm and a current rating of 4 Amperes. The component operates reliably within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• High impedance performance for effective noise suppression in power lines
• Robust thermal stability across a wide operating temperature range
• Low DC resistance to minimize power loss and voltage drop

Chip Ferrite Bead Applications

• Power line filtering in electronic circuits
• Noise suppression in high-current applications
• EMI reduction in compact surface-mount designs

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value and current rating against your circuit requirements before ordering. Confirm that the 1812 package dimensions fit your PCB layout constraints. Ensure the supplier provides official datasheets to validate the 680 Ohm specification at 100 MHz and the 30 mOhm DCR limit. Check for any manufacturer-specific handling instructions regarding thermal stress during soldering.

Chip Ferrite Bead Selection Notes

Select this component when high attenuation is required at 100 MHz for single-line power applications. The 4A current rating suits moderate-to-high current paths where low insertion loss is critical. Consider the 1812 footprint if space allows for larger components compared to smaller packages like 0805 or 0603. Evaluate thermal management needs given the wide operating temperature range.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FB series of multilayer ferrite chip beads offered by Cal-Chip Electronics. These components are designed for general-purpose EMI suppression in surface-mount technology assemblies. The series emphasizes reliability and consistent electrical characteristics across various industrial and commercial electronics applications.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must match the 680 Ohm impedance at 100 MHz, 4A current rating, and 1812 package size. Verify equivalent DCR and temperature coefficients. Cross-reference with other manufacturers' ferrite beads offering similar frequency response and current handling capabilities.
