Procurement Notes

Verify the specific capacitance value and insertion loss characteristics against the official datasheet before integration, as these parameters define the filter's performance at target frequencies. Confirm that the M3x0.5 threading matches the mounting hardware requirements of the application chassis. Ensure the 50V rating and 10A current capacity exceed the maximum expected operating conditions to guarantee long-term reliability and safety margins.

Selection Notes

Select this component when axial feedthrough topology is required for low-inductance filtering in constrained spaces. The 4400 series offers a balance of current handling and voltage rating suitable for general-purpose EMI suppression. Consider the physical dimensions and thread specification during mechanical design to ensure proper installation. Compare against other series if higher voltage ratings or different capacitance values are necessary for specific noise profiles.
