Overview
The 4311-009LF is a discoidal EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It belongs to the 4311 series and is designed for high-frequency noise suppression in electronic circuits. The component utilizes a coaxial structure with a central conductor passing through a dielectric material, providing effective attenuation of electromagnetic interference. It is packaged in bulk quantities for integration into various shielding enclosures or panel mounts.
Feature Summary
- Provides effective attenuation of electromagnetic interference signals
- Utilizes a robust discoidal physical construction for stability
- Designed for integration into shielded electronic environments
Applications
- Electronic equipment requiring EMI/RFI suppression
- Shielded enclosure installations
- Panel mount filtering applications
Procurement Notes
Verify the specific datasheet for the 4311-009LF to confirm electrical parameters such as capacitance and voltage ratings, as these are critical for circuit compatibility. Ensure the ordering suffix matches the required specifications exactly. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary. Cross-reference the part number with official CTS/Tusonix documentation to avoid substitution errors.
Selection Notes
Select this component based on its suitability for discoidal EMI filtering requirements within the 4311 series. Consider the physical dimensions and mounting style for your specific application constraints. Evaluate the need for bulk packaging versus other options if available. Ensure the component meets the environmental and regulatory standards required for your final product assembly.
Part Context
This component is part of the broader EMI feedthrough filter portfolio offered by Tusonix under the CTS Electronic Components umbrella. The 4311 series specifically focuses on discoidal designs, distinguishing it from axial or radial variants found in other series like 4200 or 4600. These filters are engineered for reliable performance in demanding electromagnetic environments.
Replacement Considerations
Consult official CTS/Tusonix cross-reference guides for verified substitutes. Generic equivalents may not match the precise electrical characteristics or physical form factor. Verify that any replacement maintains the same series designation or approved alternative part numbers listed in current manufacturer documentation.
