4401-014LF

Overview

The 4401-014LF is a bushing-style EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a C-filter circuit topology with a capacitance of 100 pF and a rated voltage of 200 V. The component supports a maximum DC current of 10 A and provides an insertion loss of 28 dB. Designed for robust performance, it operates within a temperature range of -55°C to +125°C. The physical dimensions include a diameter of 4.75 mm, classifying it as a high-reliability axial bushing filter suitable for demanding electronic environments.

Feature Summary

• Provides effective electromagnetic interference suppression through bushing-style feedthrough architecture
• Capable of handling high direct current loads up to 10 amperes
• Maintains stable electrical characteristics across extreme temperature variations from -55°C to +125°C

Applications

• High-power electronic systems requiring EMI mitigation
• Military and aerospace equipment operating in harsh thermal environments
• Industrial control units needing reliable signal integrity under high current conditions

Procurement Notes

Verify the specific suffix requirements when ordering, as the LF designation indicates lead-free compliance which may differ from standard variants. Confirm that the bushing mounting style aligns with your chassis or panel cutout specifications. Ensure the 200V rating and 10A current capacity meet your system's peak operational demands before finalizing procurement decisions.

Selection Notes

Select this component when a bushing-mount configuration is required for direct panel integration rather than PCB mounting. The 100 pF capacitance offers a specific filtering profile distinct from higher-capacitance alternatives in the 4401 series. Consider the 4.75 mm diameter for spatial constraints and verify that the 28 dB insertion loss meets your specific noise attenuation requirements at the target frequency.

Part Context

This part belongs to the Tusonix 4401 series of bushing-style EMI filters, designed for high-reliability applications. It shares the axial bushing form factor with other models in the series but differs in capacitance and voltage ratings. The series is known for providing compact, high-current filtering solutions for critical electronic systems where space and thermal stability are paramount design factors.

Replacement Considerations

The 4401-014 is a non-LF variant of this component. Verify if lead-free compliance is mandatory for your assembly process. Other series members like 4401-010LF offer different capacitance values (27 nF) and voltage ratings (70 V), requiring careful evaluation of electrical compatibility before substitution.
