EXC-ML16A270U

Chip Ferrite Bead Overview

The EXC-ML16A270U is a single-line ferrite bead chip from the Panasonic EXCML series, designed for EMI suppression in power and high-speed signal lines. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6mm x 0.8mm x 0.8mm. The component provides an impedance of 27 Ohms at 100 MHz with a tolerance of 25%. It supports a rated current of 4 Amperes and exhibits a low DC resistance of 6 milliohms. This device utilizes MLC bead core technology to effectively attenuate noise while maintaining signal integrity.

Chip Ferrite Bead Feature Summary

• Effective noise suppression for power lines and high-speed signal lines
• Low DC resistance typical of 3 to 8 milliohms for minimal voltage drop
• Easy pattern layout on printed circuit boards due to compact size
• RoHS compliant construction

Chip Ferrite Bead Applications

• Digital equipment such as PCs, word processors, printers, HDDs, and optical drives
• Digital audio and video equipment including VCRs, DVCs, CD players, and DVD players
• AC adapters and switching power supplies
• Electronic musical instruments and other digital devices

Chip Ferrite Bead Procurement Notes

Verify component status before procurement as multiple distributors list this part number as obsolete or end-of-life. Confirm availability through official Panasonic channels or authorized partners. Ensure the specific suffix matches the required impedance and current ratings. Check for RoHS compliance documentation if required by project specifications. Validate that the 0603 footprint aligns with existing PCB designs.

Chip Ferrite Bead Selection Notes

Select this component when space-constrained designs require effective EMI filtering for 4A circuits. The 27 Ohm impedance at 100 MHz targets specific noise frequencies common in digital systems. Consider the low DC resistance to minimize power loss in power delivery networks. Ensure the operating temperature range meets system requirements. Verify that the single-line configuration suits the circuit topology compared to multi-line alternatives.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the EXCML series, which focuses on low DC resistance and high current handling capabilities. The 0603 package size allows for dense PCB layouts. The EXCML series is distinct from higher impedance variants like the EXC3B series, offering a balance between attenuation and current capacity for general-purpose digital noise suppression.
