PLF-21D3-6A-Q-5

Overview

The Adam Tech PLF-21D3-6A-Q-5 is a single-phase EMI/RFI power line filter designed for chassis mounting. It operates within a voltage range of 115VAC to 250VAC and supports a current rating of 6A at 50Hz or 60Hz frequencies. The component utilizes a two-stage filtering architecture with quick-connect terminals for circuit integration. Key electrical specifications include a maximum leakage current of 1mA at 250VAC and an attenuation performance of 80dB typical at 1MHz. The unit is constructed to withstand operating temperatures up to +85°C and complies with UL, CSA, and VDE safety standards.

Feature Summary

• Two-stage EMI/RFI filtering architecture for enhanced noise suppression
• Quick-connect terminal interface for simplified circuit board integration
• Chassis mount design ensuring stable physical installation in equipment enclosures
• Compliance with major international safety certifications including UL, CSA, and VDE

Applications

• Medical imaging and diagnostic equipment requiring certified isolation
• Industrial control systems and automation machinery

Procurement Notes

Verify the specific suffix 'Q-5' against the manufacturer's latest datasheet to confirm terminal configuration and insulation clearance requirements. Ensure the selected variant matches the required voltage and current ratings for the target application. Cross-reference certification marks such as UL and VDE with the specific product label to guarantee regulatory compliance for the intended market.

Selection Notes

Select this model when a compact, single-phase solution is required for moderate current loads up to 6A. The quick-connect feature makes it suitable for designs prioritizing assembly speed over screw-terminal robustness. Evaluate the available space against the component's physical dimensions to ensure compatibility with the enclosure layout. Confirm that the operating environment temperature remains within the specified +85°C limit.
