SFCDC5000101MC0

Overview

The Knowles Syfer SFCDC5000101MC0 is a hexagonal EMI feedthrough capacitor designed for high-reliability applications. It features a capacitance of 100 pF with a ±20% tolerance and a DC voltage rating of 500 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. It employs an axial leaded package with a hexagonal flange body, facilitating secure panel mounting via threaded connections. The device is constructed for solder termination and offers high insulation resistance.

Feature Summary

• Hexagonal flange body design enables robust mechanical mounting and grounding through threaded interfaces.
• C0G (NP0) dielectric construction provides exceptional capacitance stability over varying temperatures and voltages.
• Axial lead configuration allows for direct wire connection while maintaining low parasitic inductance.

Applications

• High-frequency signal filtering in aerospace and defense electronic systems
• EMI suppression in medical imaging equipment power supplies
• Noise reduction in industrial control panels requiring rugged environmental tolerance

Procurement Notes

Verify the specific thread size and flange dimensions against the official datasheet before integration, as hexagonal feedthroughs often require precise mating hardware. Confirm RoHS compliance status and manufacturing origin if required by your supply chain standards. Ensure that the mounting torque specifications are strictly followed during installation to prevent ceramic cracking or seal failure. Cross-reference the manufacturer's latest revision notes for any changes in marking or packaging conventions.

Selection Notes

Select this component when a combination of high voltage handling, thermal stability, and secure mechanical grounding is required. The hexagonal form factor distinguishes it from cylindrical variants, offering better wrench engagement for installation. Consider the axial leads for wiring convenience in confined spaces where surface mount options are unsuitable. Evaluate the 500V rating against peak transient voltages in the circuit to ensure adequate safety margins.

Part Context

This part belongs to the Syfer SFCD series of hexagonal EMI feedthrough filters. This series is engineered for harsh environments, providing superior noise attenuation compared to standard capacitors. The hexagonal body is a key identifier within the Knowles Syfer portfolio, differentiating it from the SFBLC or SFAJC axial feedthrough lines which utilize different body shapes and mounting mechanisms.

Replacement Considerations

Direct substitutes must match the 100 pF capacitance, 500 VDC rating, and hexagonal flange geometry. Verify thread compatibility, as M2.5 to M8 sizes exist within the SFCD family. Cylindrical feedthroughs like the SFBLC series are not direct replacements due to differing mounting requirements. Consult the manufacturer's cross-reference guide for approved equivalent parts with identical electrical and mechanical profiles.
