EXC-ELSA35

Chip Ferrite Bead Overview

The EXC-ELSA35 is a single-line axial ferrite bead manufactured by Panasonic Industry. It provides an impedance of 50 Ohms at 100 MHz and supports a maximum DC current of 7 A. The component features a maximum DC resistance (DCR) of 10 mOhm. It utilizes a through-hole mounting style with axial leads. The physical dimensions are specified as 3.80 mm in diameter and 5.30 mm in length. The unit belongs to the EXCEL series and is classified under electronic filters.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression via axial ferrite core technology
• Supports high-current applications up to 7 Amperes
• Features low DC resistance for minimal signal loss

Chip Ferrite Bead Applications

• High-frequency noise filtering in power supply lines
• Electromagnetic interference (EMI) suppression in digital circuits
• Signal integrity protection in communication interfaces

Chip Ferrite Bead Procurement Notes

Verify part authenticity against Panasonic Industry documentation due to discontinued status. Confirm axial lead configuration matches PCB layout requirements. Check for alternative packaging or equivalent series components if original stock is unavailable. Ensure handling procedures account for through-hole assembly constraints.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring robust high-current handling alongside effective high-frequency attenuation. The 50 Ohm impedance at 100 MHz targets common EMI frequencies. Verify that the 7 A current rating exceeds peak operational loads. Consider the axial form factor for board space availability.

Chip Ferrite Bead Part Context

This component belongs to the EXCEL series of ferrite beads designed for general-purpose noise suppression. It serves as a passive filter element within electronic assemblies. The axial package distinguishes it from surface-mount alternatives, facilitating specific through-hole integration strategies in industrial or legacy equipment designs.

Chip Ferrite Bead Replacement Considerations

The EXC-ELSA35 is marked as obsolete. Verify compatibility with EXC-ELSA series variants or other Panasonic axial ferrite beads offering identical 50 Ohm impedance and 7 A current ratings. Cross-reference datasheets for dimensional and electrical equivalence before substitution.
