  • Backed by a two-year guarantee and supported by comprehensive technical service and testing capabilities.
FAQs:
  • What is the primary function of this EMI power line filter?
    The filter functions as an impedance adaption network to attenuate electromagnetic interference (EMI) by creating impedance mismatching between input/output sides and power/load sides, effectively smoothing DC output by reducing ripple voltage in power supplies.
  • What applications is this EMI filter suitable for?
    It's designed for various applications including industrial uses like frequency inverter drives, elevators, medical equipment, and military applications, providing noise filtration for SMPS, VFDs, and RF shielding facilities.
  • What are the key performance specifications for RF shielding effectiveness?
    The filter provides excellent shielding effectiveness: ≥60dB at 10KHz, ≥100dB from 1MHz to 18GHz, and ≥80dB from 18GHz to 40GHz, ensuring comprehensive electromagnetic compatibility across broad frequency ranges.
  • What testing standards and quality assurances does this product meet?
    Our products comply with industrial standards like IEC61800-3, EN12015, EN55011 and military standards GJB151A/GJB152A, with all products undergoing rigorous testing and backed by a two-year guarantee.
