What are the key features of 7448030509?

  • Single-phase EMI filter rated at 250V / 5A for 50Hz mains line noise suppression in industrial and consumer power supplies
  • Through-hole PCB mounting with 25mm height enables robust mechanical attachment directly to main power PCBs without additional chassis brackets
  • Broad-spectrum conducted EMI attenuation protecting sensitive downstream circuits from differential and common-mode mains interference

What is 7448030509 used for?

The 7448030509 single-phase EMI filter is used to suppress conducted electromagnetic interference on 250V AC mains power lines in industrial equipment, power supplies, and motor drives. Its 5A rated current capacity supports compressors, HVAC controllers, and variable-speed drives where mains-conducted noise must be attenuated to meet IEC 61000-3 and CISPR 22 compliance requirements. Through-hole mounting ensures reliable mechanical stability in vibration-prone environments such as factory automation and building management systems.

Frequently Asked Questions

What voltage and current ratings does Würth 7448030509 support for single-phase mains EMI filtering?

The 7448030509 is rated at 250V AC and 5A continuous current at 50Hz operating frequency. These ratings support standard European single-phase mains circuits powering equipment up to 1.25 kW, making it suitable for industrial power supplies, motor controllers, and appliances requiring conducted EMI suppression on the AC input line.

How does the through-hole mounting of 7448030509 compare to surface mount EMI filters for high-power applications?

The 7448030509 through-hole mount design with 25mm height provides superior mechanical robustness versus surface mount alternatives at 5A ratings. Through-hole leads handle higher thermal cycling stress and vibration better than SMT pads, making this filter preferable for industrial equipment, motor drives, and power conversion designs where long service life under harsh conditions is required.

Which EMC compliance standards can 7448030509 help meet in industrial power supply designs?

The 7448030509 single-phase EMI filter helps equipment meet CISPR 22/EN 55022 conducted emission limits and IEC 61000-4-4 electrical fast transient requirements in the 50Hz to 30 MHz frequency range. Using this filter on the 250V AC input reduces both common-mode and differential-mode conducted noise below Class B limits for industrial and commercial equipment certifications.
