4101-051

Overview

The 4101-051 is a Pi-type EMI feedthrough filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a chassis-mount configuration with axial eyelet terminals and one turret lead. The component provides capacitance values of 1500 pF and 3000 pF. It is rated for a maximum DC current of 10 A and has a voltage rating of 100 V. The unit operates within a temperature range of -55°C to +125°C. The physical dimensions are approximately 0.250 inches in diameter by 0.468 inches in length.

Feature Summary

• Pi-filter topology for enhanced high-frequency noise attenuation
• Chassis mounting design with axial eyelet and turret leads
• Dual capacitance specification for flexible circuit integration

Applications

• Power supply input filtering
• Electronic equipment chassis grounding
• EMI suppression in industrial control systems

Procurement Notes

Verify the specific capacitance variant required, as the part number may correspond to different internal configurations or tolerance levels. Confirm that the 10 A current rating aligns with the application's peak load requirements. Ensure the chassis mount hole size matches the 0.250-inch diameter specification. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a Pi-filter topology is necessary for superior attenuation compared to standard feedthrough capacitors. The 10 A rating suits moderate power applications requiring effective EMI reduction. Consider the axial eyelet mounting style for secure mechanical attachment to metal panels. Verify that the 100 V rating exceeds the system's operating voltage to ensure reliability under transient conditions.

Part Context

This component belongs to the 4101 series of EMI feedthrough filters from Tusonix. These filters utilize a Pi-network structure combining capacitive elements for broadband noise suppression. The series is designed for robust performance in harsh electromagnetic environments, offering reliable shielding for sensitive electronics against conducted interference.

Replacement Considerations

Direct substitutes include other Pi-filter feedthrough components with matching 10 A ratings and similar capacitance values. Ensure any replacement maintains the chassis-mount form factor and terminal configuration for compatibility with existing panel cutouts.
