RPT5500-25-S

Overview

The RPT5500-25-S is a single-stage EMI power line filter from the Astrodyne TDI RPT5000 series. It supports AC and DC applications with a voltage rating of 300 VAC and a current capacity of 25 A. The unit operates within a frequency range of 50 Hz to 400 Hz. Key electrical specifications include a leakage current of 3.5 mA. The device is designed for chassis mounting using stud termination. It functions reliably in environments ranging from -40 °C to +70 °C.

Feature Summary

• Supports TEMPEST/COTS requirements for secure signal integrity
• Single-stage design for effective noise attenuation
• Chassis mount construction with stud termination

Applications

• Secure military communication systems
• Defense avionics power conditioning
• Commercial off-the-shelf (COTS) electronic enclosures

Procurement Notes

Verify the specific datasheet version for the RPT5500-25-S to confirm compliance with current TEMPEST standards and RoHS directives. Ensure that the chassis mounting interface matches the stud termination type specified in the official documentation. Cross-reference the 300 VAC rating and 25 A current limit against the actual system load requirements before finalizing procurement decisions.

Selection Notes

Select this component when both AC and DC filtering capabilities are required within a single enclosure. The wide operating temperature range makes it suitable for harsh industrial or aerospace environments. Verify that the 3.5 mA leakage current meets safety isolation requirements for sensitive medical or precision instrumentation applications connected to the filtered power line.
