EXC-ELSA39

Chip Ferrite Bead Overview

The EXC-ELSA39 is a ferrite bead component from the Panasonic Industry EXCEL series, designed for electromagnetic interference (EMI) suppression. It features an axial package with one line and a maximum rated current of 7A. The impedance is specified as 80 Ohms at 100 MHz, while the maximum DC resistance (DCR) is 10 milliohms. The physical dimensions are 0.150 inches in diameter by 0.366 inches in length (3.80mm x 9.30mm). This through-hole device is currently marked as obsolete.

Chip Ferrite Bead Feature Summary

• Provides EMI noise suppression with high impedance characteristics at 100 MHz
• Supports high current handling up to 7A with low DC resistance
• Utilizes axial leaded construction for reliable through-hole mounting

Chip Ferrite Bead Applications

• General electronic circuit noise filtering
• Power supply line protection
• Signal integrity enhancement in digital circuits

Chip Ferrite Bead Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Panasonic Industry. Verification of availability should focus on surplus stock or authorized distributors holding remaining inventory. Substitution with equivalent ferrite beads from other manufacturers or newer Panasonic series is recommended for new designs due to discontinuation status.

Chip Ferrite Bead Selection Notes

Selection requires matching the 80 Ohm impedance at 100 MHz and 7A current rating to application needs. The axial form factor dictates through-hole PCB layout constraints. Designers must verify that the 10 milliohm DCR meets voltage drop requirements under full load conditions before integrating this specific obsolete part number.

Chip Ferrite Bead Part Context

The EXC-ELSA39 belongs to the EXCEL series of ferrite beads produced by Panasonic Industry. These components are categorized under filters and chokes, specifically ferrite beads and chips. The product falls within the broader category of passive electronic components used for signal conditioning and noise reduction in industrial and consumer electronics assemblies.

Chip Ferrite Bead Replacement Considerations

Public confirmed substitute part numbers are not provided in the source data. Designers should consult manufacturer cross-reference guides for equivalent axial ferrite beads with matching 80 Ohm @ 100 MHz impedance and 7A current ratings.
