EPZ4030U400-10R0T

Chip Ferrite Bead Overview

The EPZ4030U400-10R0T is a surface-mount ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a 1612 (4030 metric) package size and offers a nominal impedance of 40 Ohms at 100 MHz. The component utilizes a four-terminal (4LN) design to minimize inductance and enhance high-frequency noise suppression performance. It is RoHS compliant and suitable for applications requiring effective electromagnetic interference filtering in compact electronic circuits.

Chip Ferrite Bead Feature Summary

• Four-terminal structure for reduced parasitic inductance
• Ferrite material core for high-frequency noise attenuation
• Surface mount packaging for automated assembly

Chip Ferrite Bead Applications

• High-speed data line filtering
• Power supply noise suppression
• EMI reduction in portable electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'U' against the manufacturer's latest datasheet to confirm terminal configuration and impedance tolerance. Ensure the 1612 footprint matches the PCB layout. Confirm RoHS compliance status with the supplier if required for regulatory adherence. Check for any recent revisions to the part number that may affect mechanical or electrical specifications.

Chip Ferrite Bead Selection Notes

Select this component when low inductance is critical alongside high impedance. The four-terminal design provides superior performance compared to two-terminal equivalents in high-speed applications. Consider the package dimensions and thermal characteristics during board layout. Verify that the operating frequency range aligns with the target noise spectrum for effective filtering.

Chip Ferrite Bead Part Context

This part belongs to the EPZ series of ferrite beads from Sunlord, designed for general-purpose EMI suppression. The U variant typically denotes a specific internal structure optimized for low inductance. It serves as a passive component in signal integrity management, distinct from inductors or capacitors in its frequency-dependent resistive behavior.

Chip Ferrite Bead Replacement Considerations

EPZ4030D400-10R0T is a parametric equivalent with identical electrical characteristics. Both parts share the same impedance value and package type. Verify pinout compatibility before substitution. Other manufacturers' 1612 ferrite beads with 40 Ohm impedance may serve as alternatives if mechanical fit is confirmed.
