4401-004LF

Overview

The 4401-004LF is an axial feedthrough capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a 5000 pF capacitance with a tolerance range of -20% to +80%. Rated for 100 V and capable of handling 10 A DC current, this component operates within a temperature range of -55°C to +125°C. The device utilizes a bushing-style axial package with a diameter of 4.75 mm. It provides an insertion loss of 28 dB at 100 MHz and complies with RoHS3 standards.

Feature Summary

• Provides effective electromagnetic interference suppression through high insertion loss performance.
• Supports continuous direct current loads up to 10 amperes without degradation.
• Ensures operational stability across extreme environmental temperatures ranging from -55°C to +125°C.

Applications

• Power supply input filtering in electronic equipment
• EMI suppression for control signal lines
• High-current circuit protection in industrial systems

Procurement Notes

Verify the specific capacitance tolerance (-20%, +80%) against design requirements before integration. Confirm that the 10 A current rating aligns with the maximum expected load. Ensure the axial bushing package dimensions fit the designated mounting space. Check compliance with RoHS3 regulations if required by project specifications.

Selection Notes

Select this component when high current handling capability is required alongside significant EMI attenuation. The axial bushing form factor facilitates direct panel or chassis mounting. Consider the wide capacitance tolerance when precise filtering characteristics are critical. Evaluate the 100 V voltage rating against peak system voltages to ensure adequate safety margins.

Part Context

This part belongs to the Tusonix 4401 series of EMI feedthrough filters. These components are designed for robust noise reduction in demanding environments.
