Procurement Notes

Verify authenticity by purchasing exclusively through Ferroxcube's official website, authorized regional sales representatives, or officially announced distributors. Products acquired via unauthorized channels lack quality assurance and after-sales support. Confirm the specific part number matches the required impedance and current ratings before ordering to ensure compatibility with the target circuit design.

Selection Notes

Select this component when designing circuits requiring EMI suppression on low-current signal lines within 0805 footprints. Ensure the application current does not exceed the 200 mA rating to prevent saturation. Verify that the 300 ohm impedance at 100 MHz aligns with the noise spectrum of the protected signals. Consider thermal constraints and mounting orientation during layout.

Part Context

This component belongs to the MLS series of multilayer suppressors manufactured by Ferroxcube. The series targets applications demanding efficient noise filtering in digital and communication systems. The 4S7 material grade offers specific permeability characteristics suitable for broadband interference reduction in consumer electronics and computing hardware environments.

Replacement Considerations

Cross-reference with other 0805 ferrite beads offering similar 300 ohm impedance at 100 MHz and 200 mA current handling. Verify footprint compatibility and electrical parameters before substitution.
