HPR2504704Z50

Overview

The NexTek HPR2504704Z50 is a high-current DC feedthrough filter designed for robust electromagnetic interference suppression in demanding environments. It features an axial configuration with threaded terminals, facilitating secure mounting and electrical connection. The component supports a rated current of 250 Amperes and operates within a wide temperature range from -55°C to 125°C. It has a voltage rating of 500V and includes a capacitance of 0.47 µF with a tolerance of -20% to +80%. The physical dimensions are 1.250 inches in diameter by 4.000 inches in length.

Feature Summary

• High current handling capability up to 250 Amperes for power line filtering
• Threaded terminal design ensures mechanical stability and reliable electrical contact
• Wide operating temperature range suitable for extreme environmental conditions
• Axial form factor allows for direct panel or chassis mounting

Applications

• High-power DC power supply input filtering
• Industrial motor drive systems requiring EMI suppression
• Military and aerospace electronic equipment housing
• Heavy-duty renewable energy inverters and converters

Procurement Notes

Verify the specific capacitance tolerance requirements against your circuit design, as the part exhibits a wide variance (-20%, +80%). Confirm that the threaded terminal style matches your panel cutouts and mounting hardware specifications. Ensure the 250 Amp current rating aligns with peak load expectations to prevent thermal degradation. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when high current capacity is critical alongside effective EMI/RFI filtering. The axial threaded design is preferred over flange-mounted types where space constraints or existing hole patterns dictate the form factor. Consider the large physical footprint (1.250" x 4.000") during layout planning. The wide temperature range makes it suitable for applications without active cooling.

Part Context

This part belongs to the NexTek HPR250 series of high-current feedthrough filters. These components are engineered to attenuate conducted noise on DC power lines while maintaining low insertion loss at high currents. The series offers various current ratings and capacitance values to suit different power levels and filtering needs.

Replacement Considerations

Direct substitutes must match the 250A current rating, 500V voltage rating, and 0.47µF capacitance. Verify that alternative parts support the same axial threaded terminal configuration and fit within the 1.250" x 4.000" envelope. Ensure equivalent temperature performance across the -55°C to 125°C range.
