4101-001LF

Overview

The 4101-001LF is a third-order LC (Pi) EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 1500 pF and supports a maximum DC current of 10 A with a rated voltage of 200 V. The component utilizes an axial eyelet configuration with one turret lead for mounting. Designed for robust performance, it operates within a temperature range of -55°C to +125°C. This low-pass filter provides effective noise suppression in electronic circuits requiring high reliability.

Feature Summary

• Third-order LC (Pi) topology for enhanced attenuation
• Axial eyelet construction with single turret lead
• High current handling capability up to 10 A
• Wide operational temperature stability

Applications

• Electromagnetic interference suppression in sensitive electronics
• Power line filtering in industrial equipment
• Signal integrity protection in communication systems

Procurement Notes

Verify the specific package variant and lead configuration against the official datasheet before integration. Confirm that the 10 A current rating and 200 V voltage limits align with your circuit requirements. Ensure compatibility with the axial eyelet mounting style. Check for RoHS compliance status if required by your manufacturing standards. Validate thermal performance under maximum load conditions.

Selection Notes

Select this component when a third-order low-pass response is necessary for superior noise rejection compared to standard single-capacitor filters. The 1500 pF value offers a balance between capacitance and physical size for axial mounting. Consider the 10 A current capacity for power distribution applications. The wide temperature range makes it suitable for harsh environments where standard components might fail.

Part Context

This part belongs to the Tusonix family of EMI feedthrough filters, known for their compact design and high reliability. The 4101 series specifically focuses on LC (Pi) configurations, providing higher order filtering than simple capacitive types. These components are widely used in aerospace, military, and industrial sectors where signal purity and durability are critical.

Replacement Considerations

Direct substitutes may include other 1500 pF, 10 A axial Pi filters from Tusonix or compatible manufacturers. Verify pinout compatibility and mechanical dimensions before substitution. Ensure the replacement maintains the same third-order filtering characteristics and temperature ratings.
