4304-681

Overview

The 4304-681 is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 5 pF and a voltage rating of 200 V. The component supports a maximum DC current of 5 A and operates within a temperature range of -55°C to +125°C. It utilizes an axial, press-fit package with dimensions of 0.156 inches in diameter and 0.110 inches in length.

Feature Summary

• Provides electromagnetic interference suppression through low-capacitance feedthrough design
• Engineered for high-current applications with a 5 A continuous DC rating
• Constructed for robust performance across extreme industrial temperature environments

Applications

• High-frequency signal line filtering in electronic systems
• Power supply input/output noise reduction
• Shielded enclosure penetration points for cable management

Procurement Notes

Verify the specific suffix requirements for RoHS compliance, as datasheet availability varies between LF and non-LF versions. Confirm that the press-fit mounting style aligns with the target PCB or panel thickness specifications. Ensure the 200 V rating meets the system's peak voltage demands under all operating conditions.

Selection Notes

Select this component when low parasitic capacitance is critical for maintaining signal integrity at high frequencies. The axial form factor suits direct panel mounting or bulkhead installations. Compare against other series values if higher capacitance is required for different frequency attenuation profiles.

Part Context

This part belongs to the 4304 series of feedthrough capacitors from Tusonix/CTS. The series offers various capacitance values optimized for EMI suppression. The 4304-681 specifically targets applications requiring minimal signal loading while handling significant current loads in compact axial packages.

Replacement Considerations

Direct substitutes include the 4304-681LF variant, which ensures lead-free compliance. Other series members like the 4304-000 offer different capacitance values but share similar physical and electrical characteristics.
