F1199DD20

Power Line Filter Modules Overview

The F1199DD20 is a single-phase EMC/EMI power line filter manufactured by Curtis Industries. It provides radio frequency interference suppression for AC power lines operating at 50Hz or 60Hz. The component is rated for a continuous current of 20A and a maximum voltage of 250VAC. It utilizes a threaded stud mounting configuration with an 8-32 thread size, designed for secure chassis installation.

Power Line Filter Modules Feature Summary

• Provides single-stage EMI/RFI noise attenuation for AC power circuits
• Features threaded stud flange mount for robust chassis attachment
• Constructed to meet RoHS compliance standards

Power Line Filter Modules Applications

• Industrial equipment power input filtering
• Medical device power supply protection
• Commercial machinery RFI suppression

Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for the F1199DD20 to confirm exact dimensional tolerances and thermal derating curves. Ensure the mounting surface is compatible with the threaded stud specification. Confirm that the 20A current rating aligns with the system's peak load requirements without exceeding the 250VAC limit.

Power Line Filter Modules Selection Notes

Select this component when a single-phase, 20A rated filter is required for chassis-mounted applications. The 8-32 threaded post interface dictates the mechanical design of the enclosure. Consider the physical footprint and lead length constraints during PCB or panel layout planning to ensure proper clearance and strain relief.

Power Line Filter Modules Part Context

This part belongs to the Curtis Industries F1199 series of power line filters. These components are engineered for general-purpose electromagnetic interference suppression in AC environments. The series offers various current ratings and mounting options, with the F1199DD20 specifically designated for 20A single-phase applications.

Power Line Filter Modules Replacement Considerations

Direct substitutes must match the 20A current rating, 250VAC voltage rating, and 8-32 threaded stud mounting style. Verify that alternative components provide equivalent insertion loss characteristics at target frequencies. Mechanical compatibility with existing chassis holes is critical for drop-in replacement.
