Overview
The SCHAFFNER FN405-3/02 is a single-stage, single-phase EMC/EMI line filter designed to attenuate conducted electromagnetic interference on power lines. Its primary function is to ensure compliance with stringent electromagnetic compatibility standards by reducing noise ingress and egress. A critical design consideration for this 3A, 250VAC rated component is the trade-off between filter effectiveness and insertion loss; while higher inductance values (2mH) provide superior attenuation, they can also introduce undesirable voltage drops and power dissipation, necessitating careful impedance matching in the power supply design.
Key Features
- Current Rating: 3 A
- AC Voltage Rating: 250V
- Frequency Range: DC ~ 400Hz
- Inductance: 2mH
- Configuration: Single Stage
- Mounting Type: Through Hole (PC Pins)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Power line noise suppression in industrial automation equipment
- EMI reduction in medical device power supplies
- Filtering for motor drives and variable frequency inverters
- Ensuring signal integrity in sensitive test and measurement instrumentation
