Features and Benefits

  • Outstanding high-frequency filtering performance: Compared to ordinary filters, the through-hole structure reduces parasitic parameters of circuit leads, offering better interference attenuation at high frequencies (such as 1MHz–1GHz), making it suitable for devices sensitive to high-frequency interference.
  • Strong electromagnetic shielding: The metal casing forms a closed shielding cavity, preventing interference ‘diffraction’, and is especially suitable for environments with complex electromagnetic conditions (such as industrial control cabinets and communication equipment compartments).
  • Easy installation and grounding: Panel-mounted installation requires no complex fixing structures, the casing is directly grounded, providing a short grounding path with low impedance, greatly improving interference dissipation efficiency.
