4206-006LF

Overview

The 4206-006LF is a Pi filter EMI feedthrough component manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 3000 pF and supports a maximum DC current of 25 A with a voltage rating of 1 kV. The device utilizes an axial bushing package with two notched leads for chassis mounting. Designed as a third-order low-pass filter, it operates within a temperature range of -55°C to +125°C. The unit weighs approximately 5 grams and is supplied in bulk packaging.

Feature Summary

• Provides third-order low-pass filtering for effective EMI/RFI suppression
• Features axial bushing construction with dual notched leads for secure panel mounting
• Supports high current loads up to 25 A at elevated temperatures

Applications

• Chassis-mounted power line filtering
• High-voltage DC circuit protection
• Industrial equipment EMI suppression

Procurement Notes

Verify the specific voltage rating requirements against the 1 kV specification provided in distributor documentation. Confirm that the axial bushing form factor with notched leads aligns with the mechanical design constraints of the target enclosure. Ensure the operating environment remains within the specified -55°C to +125°C thermal limits for reliable performance.

Selection Notes

Select this component when a robust, high-current feedthrough solution is required for chassis installation. The 3000 pF capacitance offers a balance between filtering efficacy and physical size. Consider the 1 kV rating for applications requiring higher voltage isolation compared to standard 100 V or 500 V variants in the same series.

Part Context

This component belongs to the 4206 series of EMI feedthrough filters from Tusonix. These devices are engineered for high-reliability environments where space-constrained, high-performance filtering is necessary. The series typically includes various capacitance values to suit different frequency attenuation needs while maintaining consistent mechanical mounting standards.

Replacement Considerations

Cross-reference part numbers such as M15733/61-0003 for military-grade equivalents. Verify that any substitute maintains the 25 A current rating and 1 kV voltage capability to ensure system integrity.
