SFJEC2K00471MC1

Overview

The Knowles Syfer SFJEC2K00471MC1 is an axial feedthrough capacitor with a capacitance of 470 pF and a voltage rating of 2 kV. It features a bushing mounting style and supports a current of 15 A. The component utilizes a ceramic dielectric construction suitable for high-frequency filtering applications.

Feature Summary

• Axial leaded feedthrough design with bushing termination
• High voltage capability rated at 2 kV DC
• Supports continuous current handling up to 15 A
• Compact 470 pF capacitance for RF noise suppression

Applications

• RF signal line filtering in communication systems
• Power supply input/output decoupling for high-voltage circuits
• EMI suppression in aerospace and military electronic assemblies
• Feedthrough filtering in shielded enclosures and connectors

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Knowles Syfer before procurement, as environmental certifications may vary by production batch. Confirm that the axial bushing footprint matches the mechanical constraints of the target enclosure. Ensure that the 15 A current rating and 2 kV breakdown voltage align with the system's operational stress limits to prevent premature failure or insulation breakdown during high-stress transient events.

Selection Notes

Select this component when axial feedthrough topology is required for superior EMI shielding compared to surface mount alternatives. The 2 kV rating distinguishes it from lower-voltage MLCCs, making it suitable for high-potential isolation needs. Consider the 15 A current capacity against the load requirements. This part is ideal for applications demanding robust grounding paths through chassis walls where space allows for bushing-style installation rather than standard PCB-mounted capacitors.

Part Context

The SFJEC series represents Knowles Syfer's specialized line of feedthrough capacitors designed for high-reliability environments. These components integrate the capacitor element directly into the connector or panel mount structure, providing a low-inductance path to ground. This architecture minimizes parasitic effects often associated with traditional discrete capacitor installations, ensuring effective high-frequency noise attenuation in sensitive RF and power electronics.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific axial feedthrough model. Alternative solutions may require redesigning the mechanical interface to accommodate different form factors such as SMD or radial leaded variants, which would alter the grounding strategy and PCB layout requirements.
