RPT5000-35-S

Overview

The Astrodyne TDI RPT5000-35-S is a DC EMI power line filter designed for robust multi-stage suppression of conducted electromagnetic interference. It features a three-stage filtering architecture with threaded post (M5) terminations. The unit supports a current rating of 35 A and operates at voltages up to 400 VDC, with a maximum operating voltage of 1500 VDC. The device functions within an ambient temperature range of -40°C to 100°C. It is constructed for chassis mounting applications requiring reliable signal integrity in demanding environments.

Feature Summary

• Provides multi-stage suppression of conducted electromagnetic interference for DC systems
• Features TEMPEST/COTS compliance for secure electronic applications
• Utilizes threaded post (M5) termination style for secure mechanical connection

Applications

• DC power line filtering in industrial equipment
• Electromagnetic compatibility enhancement for sensitive electronic systems
• Chassis-mounted noise reduction in military or aerospace DC power architectures

Procurement Notes

Verify the specific suffix 'S' confirms the threaded post termination style required for your chassis mounting configuration. Confirm that the 35 A current rating and 400 VDC operating voltage align with your system's electrical requirements. Ensure the -40°C to 100°C operating temperature range meets your environmental conditions. Cross-reference the manufacturer part number directly with official Astrodyne TDI documentation to ensure authenticity and correct specification matching before purchase.

Selection Notes

Select this component when a DC EMI filter with a 35 A capacity and M5 stud terminations is required. The three-stage design offers enhanced attenuation compared to single-stage alternatives. Consider the physical dimensions and thermal management capabilities if installing in enclosed spaces. Verify that the TEMPEST/COTS classification is necessary for your security or commercial off-the-shelf requirements. Ensure the input voltage does not exceed the 1500 VDC maximum limit.

Part Context

This model belongs to the Astrodyne TDI RPT5000 series of DC EMC/EMI line filters. The series provides various current ratings and termination options for different DC power applications. The RPT5000-35-S specifically denotes the 35 Ampere variant with stud-style connections. This series is engineered for high-reliability environments where conducted noise suppression is critical for system stability and compliance.

Replacement Considerations

Direct substitutes must match the 35 A rating, 400 VDC operation, and M5 threaded post termination. Verify that any alternative maintains the three-stage filtering topology and similar TEMPEST/COTS compliance status. Physical footprint and mounting hole patterns must be compatible with existing chassis designs. Consult official manufacturer cross-reference lists for validated equivalent part numbers.
