The 4206-030LF is a Pi-filter EMI feedthrough capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 3000 pF with a voltage rating of 1 kV and a maximum DC current handling capacity of 25 A. The component utilizes a bulk packaging format and operates within a temperature range of -55°C to +125°C. Its physical dimensions include a diameter of 0.375 inches and a height of 0.687 inches. This axial leaded device provides high isolation for electromagnetic interference suppression in power applications.
Verify the specific suffix LF indicates lead-free compliance when sourcing. Confirm that the 1 kV rating aligns with peak transient requirements rather than just steady-state DC. Ensure mechanical clearance accommodates the 0.687-inch height dimension during panel cutout preparation. Cross-reference datasheet revision dates to confirm parameter stability before finalizing procurement orders.
Select this model when high-voltage isolation is required alongside significant current carrying capacity. The Pi-filter configuration offers superior attenuation compared to single-capacitor designs. Evaluate thermal dissipation needs as the component handles substantial DC loads. Consider the axial lead form factor for through-hole mounting constraints in dense assemblies.
This component belongs to the 4206 series of EMI feedthrough filters designed by Tusonix. The series focuses on providing robust electromagnetic compatibility solutions for demanding environments. These filters are engineered to meet strict regulatory standards for conducted emissions. The product line emphasizes reliability and consistent performance across wide temperature ranges.
