Overview
The PLF-21F2-40A-S is a single-phase EMI/RFI power line filter manufactured by Adam Tech. It features a dual-stage filtering architecture designed for high-current applications. The unit supports voltage ratings of 115 VAC and 250 VAC with a continuous current rating of 40 A. It operates at frequencies of 50 Hz and 60 Hz. The component utilizes screw terminal termination for secure electrical connections and is designed for chassis mounting. Key electrical specifications include an inductance of 2 x 1.2 mH and capacitance values of 0.47 uF and 6800 pF.
Feature Summary
- Dual-stage EMI/RFI filtering architecture
- High current capacity of 40 Amperes
- Screw terminal termination for robust connection
- Chassis mount design for industrial integration
Applications
- General purpose industrial equipment
- Power supply input stages
- Electromagnetic compatibility compliance systems
Procurement Notes
Verify the specific datasheet version to confirm mechanical dimensions and terminal pitch before integration. Ensure the mounting surface can support the thermal load generated during operation at full rated current. Confirm that the screw terminals match the available fastener specifications in the target assembly. Check for regional availability restrictions as distribution may vary by location.
Selection Notes
Select this model when a dual-stage filter is required for 40 A circuits operating at standard utility frequencies. The large outline package accommodates the necessary components for effective noise suppression at high currents. Verify that the chassis mounting style fits the enclosure design constraints. Ensure the voltage rating aligns with the local mains supply configuration.
Part Context
This component belongs to the PLF series of power line filters from Adam Tech. The series includes various configurations for different current and voltage requirements. The PLF-21F2-40A-S represents a high-current variant within this lineup, distinguished by its 40 A rating and dual-stage construction. It is part of a broader range of EMC solutions offered by the manufacturer.
Replacement Considerations
Direct substitutes must match the 40 A current rating, 115/250 VAC voltage rating, and dual-stage topology. Verify that any replacement maintains the same chassis mount footprint and screw terminal interface. Cross-reference inductance and capacitance values to ensure equivalent filtering performance.
