Overview
The AMFE30503-LN11 is a passive AC EMC filter designed for PCB mounting. It supports an input voltage range of 85-305VAC with a maximum current rating of 0.3A. The component provides surge suppression capabilities of 1kV between Line and Neutral, and 2kV between Line and Ground. It ensures electrical isolation of 2000VAC. The unit operates within a temperature range of -40°C to +85°C and complies with EN55032 Class B EMI standards.
Feature Summary
- Passive electromagnetic compatibility filtering for AC power lines
- Integrated surge suppression protection against transient voltages
- High isolation voltage capability for safety compliance
- Compliance with EN55032 Class B emission standards
Applications
- Input stage filtering for AC-DC converters
- Industrial equipment requiring EMI suppression
- Power supplies operating in harsh thermal environments
Procurement Notes
Verify the specific suffix LN11 to confirm the exact surge rating and package configuration. Confirm availability status as this series may be discontinued or subject to limited stock. Ensure the application voltage does not exceed the 305VAC limit. Check for required mounting hardware compatibility with PCB hole patterns.
Selection Notes
Select this component when low current applications require robust surge protection alongside EMI filtering. The 0.3A rating limits suitability for higher power loads. Verify that the 2000VAC isolation meets system safety requirements. Consider the industrial temperature range if ambient conditions vary significantly.
Part Context
This part belongs to Aimtec's AMFE30503 series of AC EMC filters. These components are engineered to protect downstream electronics from power line disturbances. The series focuses on providing reliable noise reduction and surge defense for compact power conversion systems.
Replacement Considerations
Check Aimtec datasheets for other AMFE305xx series variants with matching current ratings. Verify equivalent surge suppression levels and isolation voltages before substitution. Ensure physical footprint compatibility for direct replacement.
