EXC-ELSR35S

Chip Ferrite Bead Overview

The EXC-ELSR35S is a single ferrite bead core manufactured by Panasonic Electronic Components, designed for EMI suppression in electronic circuits. It features an axial leaded configuration with a kinked radial bend, facilitating easy integration into printed circuit boards and wire harnesses. The component exhibits a nominal impedance of 50 Ohms at 100 MHz, providing effective attenuation of high-frequency noise. It supports a peak current rating of 7A and maintains a maximum DC resistance of 10mOhm to minimize signal loss. The physical dimensions include a diameter of 3.80mm and a maximum height of 14.50mm, ensuring compatibility with standard mounting requirements.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference (EMI) suppression through high impedance characteristics at target frequencies.
• Features a robust axial lead design with a kinked radial bend for secure mechanical attachment and simplified routing.
• Capable of handling high peak currents up to 7A without saturation, suitable for power line applications.

Chip Ferrite Bead Applications

• Noise filtering on DC power supply lines
• Signal integrity improvement in data communication cables
• EMI suppression in automotive electronic modules

Chip Ferrite Bead Procurement Notes

Verify the exact part number spelling, as variations such as EXCELSR35S may appear in distributor databases. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Ensure the axial lead style matches your PCB footprint or wiring harness requirements before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required alongside moderate impedance values. The 50 Ohm impedance at 100 MHz makes it suitable for general-purpose noise suppression rather than precise RF filtering. Consider the physical size constraints, as the 14.50mm height requires adequate clearance in enclosed assemblies.

Chip Ferrite Bead Part Context

This component belongs to the EXCEL series of ferrite beads from Panasonic, which are engineered for reliable performance in demanding environments. The series offers various impedance and current ratings to suit different application needs. As a passive EMI suppressor, it complements other filtering components like capacitors and inductors in comprehensive noise reduction strategies.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must match the 50 Ohm @ 100 MHz impedance, 7A current rating, and axial form factor. Verify that alternative ferrite cores have compatible DC resistance and physical dimensions to ensure fitment without redesigning the mounting structure.

Chip Ferrite Bead FAQ

What is the operating frequency range for optimal noise suppression?

The component is rated at 50 Ohms specifically at 100 MHz, indicating its primary effectiveness in the high-frequency range typical for digital noise and EMI.

Can this ferrite bead be used in AC applications?

While primarily designed for DC lines, the 7A peak current rating suggests it can handle significant current loads; however, specific AC voltage ratings should be confirmed with manufacturer datasheets for safety.
