4311-005

Overview

The 4311-005 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 electromagnetic interference suppression in electronic circuits. The component features a robust discoidal package suitable for panel mounting applications. It operates within a temperature range of -55°C to 125°C and complies with RoHS standards where applicable (e.g., 4311-005LF variant). The device provides effective filtering for high-frequency noise while maintaining structural integrity under various environmental conditions.

Feature Summary

• Discoidal physical form factor designed for secure panel mounting
• Engineered for electromagnetic interference (EMI) suppression
• Capable of operating across a wide industrial temperature range

Applications

• Electromagnetic compatibility (EMC) filtering in electronic assemblies
• Panel-mounted signal or power line noise reduction
• Industrial equipment requiring robust EMI protection

Procurement Notes

Verify the specific suffix (e.g., LF for lead-free) against project requirements, as availability varies by variant. Confirm current stock status with distributors due to restricted supply indications. Ensure the selected part number matches the exact electrical and mechanical specifications required for the design. Check for any regional sales restrictions before ordering.

Selection Notes

Select this component when a discoidal feedthrough filter is required for panel mounting. Compare capacitance and voltage ratings against other series like 4702 if different form factors are needed. Ensure the operating temperature range meets the application's environmental demands. Verify compliance requirements such as RoHS if using non-LF variants.

Part Context

Tusonix specializes in EMC products, including feedthrough capacitors and filters. The 4311 series represents their discoidal filter line, offering reliable EMI suppression. These components are integral to maintaining signal integrity in noisy environments. The manufacturer's focus on robust design ensures performance in demanding industrial and commercial applications.

Replacement Considerations

Check for direct substitutes within the 4311 series with matching capacitance and voltage ratings. Consider alternative series like 4702 if a pill-shaped package is acceptable. Verify that any replacement maintains the same mounting style and electrical characteristics.
