Procurement Notes
Verify the complete part number including the suffix MXT to ensure correct tape-and-reel packaging configuration. Confirm RoHS3 compliance status as required by specific environmental regulations. Cross-reference the manufacturer datasheet for precise footprint dimensions and soldering profile recommendations to ensure reliable surface mount assembly.
Selection Notes
Select this component when high current capacity and compact surface-mount form factor are required. The 2220 package offers a balance between capacitance value and board space efficiency. Ensure the operating voltage does not exceed 500 V DC and that the ambient temperature remains within the specified -55°C to +125°C range for optimal performance.
Part Context
This component belongs to the SBSMC series of feedthrough capacitors from Knowles Syfer. These devices integrate capacitor technology into a single surface-mount package, replacing traditional discrete components. The series is engineered for high reliability in demanding environments, offering superior noise attenuation compared to standard MLCCs while maintaining structural integrity under thermal stress.
Replacement Considerations
Direct substitutes include other SBSMC series variants with matching capacitance and voltage ratings, such as SBSMC5000473MXT or SBSMC5000153MXT, provided pin compatibility and current ratings align with design requirements.
