Overview
The Würth Elektronik WE-CLFS 810911003 is a single-phase EMC/EMI power line filter designed for chassis mounting. It operates at a rated voltage of 250 VAC and supports a continuous current of 3 A at frequencies of 50 Hz and 60 Hz. The component utilizes Faston quick-connect terminals for circuit integration. It provides broadband noise suppression in both common and differential modes, ensuring effective electromagnetic interference mitigation for AC power applications.
Feature Summary
- Provides broadband noise suppression in common and differential modes
- Utilizes Faston quick-connect terminals for easy circuit integration
- Designed for single-phase AC power line filtering applications
Applications
- AC power input stages in electronic equipment
- Electromagnetic compatibility (EMC) compliance systems
- Chassis-mounted industrial control units
Procurement Notes
Verify the specific datasheet version to confirm terminal dimensions and mounting hole specifications. Ensure the application environment does not exceed the 250 VAC rating or 3 A current limit. Confirm RoHS compliance status through official manufacturer documentation before final procurement decisions.
Selection Notes
Select this component when single-stage filtering is sufficient for the target EMI profile. The 3 A rating suits moderate power loads. Verify that the Faston terminal style matches existing PCB or wire harness connectors. Consider thermal management requirements if operating near maximum current ratings.
Part Context
This part belongs to the WE-CLFS series from Würth Elektronik, which specializes in single-phase power line filters. These components are engineered for robust performance in standard AC mains environments. The series offers various current ratings to accommodate different power consumption levels across diverse electronic devices.
Replacement Considerations
Direct substitutes must match the 3 A current rating, 250 VAC voltage, and Faston terminal configuration. Verify identical physical dimensions for chassis mounting compatibility. Ensure equivalent attenuation characteristics in the required frequency bands to maintain system EMC integrity.
