4305-001LF

Overview

The 4305-001LF is an EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 100 pF and a voltage rating of 200 V DC. The component supports a maximum DC current of 5 A and operates within a temperature range of -55°C to +125°C. It utilizes a solder mount axial package with dimensions of 3.55 mm in diameter and 10.16 mm in length. The lead diameter measures 0.76 mm, and the unit weighs approximately 190 mg.

Feature Summary

• Provides electromagnetic interference suppression through high-frequency signal attenuation via integrated capacitance.
• Designed for direct panel mounting using a threaded or press-fit axial configuration for secure installation.
• Constructed to maintain electrical stability across extreme environmental temperatures ranging from -55°C to +125°C.

Applications

• Power supply input filtering in electronic equipment
• Signal line protection in communication systems
• EMI mitigation in aerospace and military avionics

Procurement Notes

Verify the specific datasheet version for the 4305-001LF to confirm RoHS compliance status and REACH SVHC declarations, as these details are listed as variable in source documentation. Ensure that the 200 V DC rating aligns with your system's operational requirements rather than the potentially conflicting 300 V mention found in some summaries. Confirm the axial package dimensions match your panel cutout specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-capacitance feedthrough solution is required for high-current applications up to 5 A. The 100 pF value makes it suitable for attenuating high-frequency noise without significantly affecting lower frequency signals. Consider the axial form factor for applications requiring robust mechanical mounting directly onto chassis panels or bulkheads.

Part Context

This part belongs to the 4305 series of EMI feedthrough filters produced by Tusonix / CTS. The series offers various capacitance values tailored for different filtering needs. The 4305-001LF specifically addresses scenarios requiring minimal capacitance alongside high current handling capabilities, distinguishing it from higher capacitance variants in the same product family.

Replacement Considerations

Publicly confirmed substitute part numbers for the 4305-001LF were not identified in the provided source material. Verify compatibility with alternative feedthrough capacitors based on matching capacitance, voltage ratings, and physical dimensions if substitution is necessary.
