F1399DD20

Power Line Filter Modules Overview

The Curtis Industries F1399DD20 is a single-phase EMC/EMI power line filter module designed for chassis mounting. It features a two-stage filtering configuration to suppress electromagnetic and radio frequency interference in AC power circuits. The unit is rated for a continuous current of 20 A at an AC voltage of 250 V, operating within the standard 50/60 Hz frequency range. Termination is achieved via threaded posts with 8-32 threading, providing secure mechanical and electrical connections for industrial applications requiring robust noise suppression.

Power Line Filter Modules Feature Summary

• Two-stage EMI/RFI filtering architecture for enhanced noise attenuation
• Threaded post termination (8-32) for secure chassis integration
• Single-phase design optimized for AC power line protection

Power Line Filter Modules Applications

• Industrial machinery power input stages
• Medical equipment power supplies
• Commercial electronic systems requiring EMI compliance

Power Line Filter Modules Procurement Notes

Verify that the application requires a 20 A rating and 8-32 threaded post termination, as these are specific to the F1399DD20 variant. Confirm chassis mounting compatibility and panel cutout dimensions prior to installation. Ensure the system operates within the 250 VAC and 50/60 Hz specifications. Cross-reference certification requirements such as UL or TUV if mandated by the end-use environment.

Power Line Filter Modules Selection Notes

Select this component when high-current single-phase filtering is required with threaded post connections rather than quick-connect terminals. Compare against the F1399CA10 for lower current needs or different termination styles. Ensure the physical footprint fits the designated chassis space. Validate that the two-stage performance meets the specific EMI/RFI suppression standards applicable to the target equipment.

Power Line Filter Modules Part Context

The F1399DD20 belongs to the Curtis Industries F1399 series of power line filters. This series includes various configurations differentiated by current ratings, termination types, and mounting styles. The F1399AA02 serves as a similar low-current alternative with quick-connect terminals, while the F1399DD20 specifically addresses higher current demands using threaded hardware for robust connection integrity.
