Power Line Filter Modules datasheet and documents for TFI 300

TFI 300

Power Line Filter Modules Overview

The TFI 300 is a 300W power line surge filter designed for PCB mounting in plastic cases. It operates within a voltage range of 43 VDC to 160 VDC and withstands temperatures from -40°C to +95°C. The unit features solder pin termination and measures 25.4 mm in length, 10.4 mm in width, and 40.6 mm in height, weighing 22 g. It clamps over-voltage transients to protect downstream DC/DC converters, handling surges up to 385V DC for 20ms per RIA12 standards.

Power Line Filter Modules Feature Summary

Clamps momentary over-voltage transients to safe values to protect DC/DC converters
Complies with the strict RIA12 standard for railway transient immunity
Maintains output voltage tracking input voltage during normal operation

Power Line Filter Modules Applications

Railway applications requiring high voltage transient protection
72V DC battery systems in railway environments
96V DC battery systems in railway environments
110V DC battery systems in railway environments

Power Line Filter Modules Procurement Notes

Verify the specific manufacturer part number against official TRACO Power documentation to ensure authenticity. Confirm that the component meets the required RIA12 standard compliance for your specific application environment. Check the operating temperature range specifications against your system's thermal conditions. Ensure the physical dimensions fit your PCB layout constraints.

Power Line Filter Modules Selection Notes

Select this component when protecting sensitive DC/DC converters from high-energy surges in railway or heavy-duty industrial settings. It is suitable for systems operating between 43V DC and 160V DC. Consider the PCB mount form factor and solder pin termination style for integration. Evaluate the need for RIA12 compliance if the application involves significant transient voltage events.

Power Line Filter Modules Part Context

The TFI 300 belongs to the TFI series of power line surge filters from TRACO Power, which includes 20W and 150W variants. These filters are positioned upstream of DC/DC converters to mitigate electromagnetic interference and voltage spikes. The series is engineered to handle strict transient definitions, ensuring robust performance in electrically noisy environments typical of rail transport.
