4404-003LF

Overview

The 4404-003LF is an EMI feedthrough capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 0.1 uF and a rated voltage of 100 V. The component supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. It utilizes an axial bushing package with an 8-32 UNC-2A thread size. Physical dimensions include a diameter of 0.187 inches, a length of 0.749 inches, and a height of 0.389 inches. Insertion loss is specified at 47 dB @ 100MHz.

Feature Summary

• Provides electromagnetic interference suppression through feedthrough filtering architecture
• Features axial bushing mounting configuration for panel integration
• Supports high current handling capabilities suitable for power line applications

Applications

• Electromagnetic interference filtering in electronic equipment
• Power supply input stages requiring feedthrough capacitance
• Panel-mounted filter installations using threaded bushing interfaces

Procurement Notes

Verify the specific suffix requirements against the manufacturer datasheet to ensure compliance with RoHS standards and lead-free specifications. Confirm that the 8-32 thread size matches the intended panel cutout and mounting hardware. Check for any environmental certifications required for the target application region. Ensure the operating temperature range aligns with the system's thermal profile.

Selection Notes

Select this component when a 0.1 uF capacitance value is required for EMI suppression on lines carrying up to 10 A. The 100 V rating must exceed the maximum circuit voltage. The axial bushing form factor dictates the mechanical installation method. Consider the 47 dB insertion loss performance at 100 MHz for noise attenuation requirements.

Part Context

This part belongs to the 4404 series of EMI feedthrough filters from Tusonix. The series offers various capacitance values and voltage ratings. The 4404-003LF specifically targets applications needing moderate capacitance with robust current handling. It is distinct from the 4702 series which uses a pill package.
