4251-002LF

Overview

The 4251-002LF is an LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 0.012 µF and supports a maximum DC current of 10 A. Rated for 100 V, this third-order low-pass filter operates within a temperature range of -55°C to +125°C. The component utilizes an axial bushing package with dimensions of 0.187 inches in diameter and 0.470 inches in length.

Feature Summary

• Provides effective electromagnetic interference suppression through a third-order low-pass LC Pi-filter topology.
• Designed for high-current applications with a 10 A rating and robust chassis mounting via an axial bushing configuration.

Applications

• Power line filtering in industrial equipment
• EMI suppression in military and aerospace systems
• Signal conditioning in medical devices

Procurement Notes

Verify the specific capacitance tolerance and voltage derating requirements against your system's operational limits before integration. Confirm that the axial bushing mounting style aligns with your chassis design constraints. Ensure compliance with RoHS3 standards if required by your supply chain regulations.

Selection Notes

Select this component when a third-order attenuation profile is necessary for high-current power lines. The 10 A rating distinguishes it from lower-capacity feedthrough capacitors. Consider the physical dimensions of the axial bushing package to ensure adequate clearance on the mounting panel.

Part Context

This part belongs to the 4251 series of EMI/RFI filters produced by Tusonix. These components are engineered for demanding environments requiring reliable noise reduction. The series offers various capacitance values tailored for different frequency attenuation needs while maintaining consistent mechanical mounting standards.

Replacement Considerations

Direct substitutes include other 4251-series variants with similar capacitance and current ratings. Verify pin compatibility and mounting hole alignment when cross-referencing with generic LC Pi-filters from other manufacturers.
