Overview
The NexTek HPR4004704Z50 is a high-current feedthrough EMI/RFI filter belonging to the HPR400 series. It features an axial package with threaded terminals and utilizes bolt mounting for secure installation. The component has a rated voltage of 500V and supports a continuous current of 400 A. It incorporates a capacitance value of 0.47µF within its LC or RC network structure. The device operates reliably within a temperature range of -55°C to 125°C.
Feature Summary
- High-current feedthrough design for robust power line filtering
- Axial package with threaded terminals enabling direct bolt mounting
- LC/RC network configuration for effective EMI and RFI suppression
Applications
- Industrial power distribution systems requiring high-current filtering
- Military and aerospace electronic equipment chassis grounding
- Heavy-duty machinery control panels
Procurement Notes
Verify the specific datasheet version to confirm terminal thread dimensions and torque specifications before integration. Ensure the mounting surface provides adequate electrical grounding as required by the feedthrough architecture. Cross-reference the 400 A rating with actual system load profiles to prevent thermal overload during operation.
Selection Notes
Select this component when high-current capacity and rigid mechanical mounting are required for EMI suppression. The threaded terminal design facilitates secure connections in vibration-prone environments. Consider the 500V rating and 0.47µF capacitance to ensure compatibility with the target circuit's voltage levels and filtering requirements.
Part Context
This part belongs to the NexTek HPR400 series, which specializes in high-current feedthrough filters. These components are designed for applications where standard through-hole or surface-mount filters cannot handle the required current loads or mechanical stresses. The series typically offers robust construction for demanding industrial and defense sectors.
Replacement Considerations
No public confirmed substitute part numbers are available for this specific model.
