SBSGC5000333MXT

Overview

The Knowles Syfer SBSGC5000333MXT is a surface mount feedthrough capacitor designed for EMI filtering. It features a capacitance of 0.033 µF with a ±20% tolerance and a DC voltage rating of 500V. The component utilizes an X7R dielectric material, ensuring stability across a wide operating temperature range from -55°C to +125°C. Rated for a continuous current of 10A, it is housed in a compact 1812 (4532 Metric) package with a three-pad surface mount configuration.

Feature Summary

• Surface mount C and PI filter topology for effective electromagnetic interference suppression
• High current handling capability suitable for power line applications
• Robust X7R ceramic dielectric for stable performance under thermal stress

Applications

• Electromagnetic interference filtering in electronic circuits
• Power supply input stages requiring high current capacity
• Signal conditioning in sensitive communication equipment

Procurement Notes

Verify the specific suffix MXT indicates tape and reel packaging when ordering. Confirm the 1812 footprint dimensions match your PCB layout constraints. Ensure the 500V DC rating meets your circuit's maximum operating voltage requirements. Check RoHS compliance status if required by your manufacturing standards. Validate the 10A current rating against peak load conditions.

Selection Notes

Select this component when surface mount integration is required for feedthrough filtering. The 1812 package offers a balance between current capacity and board space efficiency. Consider the X7R temperature coefficient for environments with significant thermal fluctuations. The 10A rating distinguishes it from lower-current SMD alternatives. Verify compatibility with standard reflow soldering profiles for three-pad terminations.

Part Context

This part belongs to the SBSG series of surface mount feedthrough capacitors from Knowles Syfer. These components are engineered to replace traditional through-hole feedthroughs in modern PCB designs. The series provides high-frequency noise attenuation while maintaining low impedance paths for power signals. They are commonly used in aerospace, defense, and industrial electronics where reliability is critical.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to the specific three-pad surface mount geometry. Evaluate other SBSG series variants with similar capacitance and voltage ratings if exact matches are unavailable. Ensure any substitute maintains the 10A current rating and 1812 footprint. Verify that alternative components support the same X7R dielectric characteristics for thermal stability.
