SFSWG5000472MX0

Overview

The Knowles Syfer SFSWG5000472MX0 is a flange-mounted feedthrough capacitor designed for high-frequency EMI suppression. It features a capacitance of 4.7 nF with a tolerance of ±20%. The component is rated for a DC voltage of 500 VDC and supports a maximum current of 5 A. Constructed with C0G dielectric, it operates within a temperature range of -55°C to +125°C. The physical dimensions include a diameter of 3.25 mm and a length of 3.29 mm. It utilizes a solder termination type and is supplied in bulk packaging.

Feature Summary

• Flange end seal construction for secure panel mounting
• C0G dielectric material ensuring stable capacitance characteristics
• High current handling capability of 5 A
• Low parasitic inductance design for effective high-frequency filtering

Applications

• RF and microwave circuit shielding
• Military and aerospace electronic systems
• Medical equipment power filtering
• Industrial control system EMI suppression

Procurement Notes

Verify the specific suffix MX0 against the manufacturer's latest datasheet to confirm package and tolerance variations. Ensure compatibility with existing panel cutouts due to the fixed flange dimensions. Confirm RoHS compliance status if required by your supply chain standards. Check lead times as production cycles may vary significantly based on current demand and manufacturing schedules.

Selection Notes

Select this component when a robust, hermetically sealed feedthrough solution is required for 500V applications. The 4.7 nF value provides a balance between low-pass filtering and signal integrity for specific frequency bands. Consider the 5A current rating against your circuit's peak load requirements. The C0G dielectric is suitable for applications demanding minimal capacitance drift over temperature changes compared to X7R alternatives.

Part Context

This part belongs to the SFSWG series of feedthrough capacitors from Knowles Syfer. The series is characterized by its flange-mount style, which facilitates direct installation into chassis panels or enclosures. These components are engineered to provide superior electromagnetic interference protection in harsh environments, distinguishing them from standard surface-mount or through-hole ceramic capacitors.

Replacement Considerations

Direct substitutes must match the 500V rating, 4.7nF capacitance, and flange mounting geometry. Verify that any alternative component maintains the same terminal configuration and dimensional constraints to ensure fitment without modifying the host enclosure.
