SBSMC2000154MXR

Overview

The Knowles Syfer SBSMC2000154MXR is a surface mount feedthrough capacitor designed for EMI suppression. It features a capacitance of 0.15 µF with a ±20% tolerance and a rated voltage of 200V. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Packaged in a Tape & Reel (TR) format, it measures 5.70mm x 5.00mm x 3.38mm. This device provides high insertion loss performance, specifically 43dB at 100MHz, making it suitable for filtering applications in compact electronic designs.

Feature Summary

• Surface mount feedthrough architecture for efficient PCB integration
• High insertion loss performance for effective EMI suppression
• X7R dielectric material for stable capacitance over temperature variations

Applications

• Power supply input filtering
• Signal line noise reduction
• Embedded system EMI mitigation

Procurement Notes

Verify the specific suffix MXR indicates the Tape & Reel packaging configuration when sourcing. Confirm the 200V rating and 0.15 µF capacitance match the circuit requirements. Ensure compatibility with surface mount assembly processes. Check for RoHS compliance status if required by project specifications. Validate the active part status with the manufacturer or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component for applications requiring compact EMI filtering with moderate capacitance values. The 200V rating suits low-to-medium voltage DC lines. Consider the 2220 package size for space-constrained layouts. The X7R characteristic offers good temperature stability compared to lower-grade ceramics. Evaluate the 43dB insertion loss at 100MHz against specific noise frequency profiles to ensure adequate attenuation.

Part Context

This part belongs to the SBSM series of feedthrough capacitors from Knowles Syfer. These components are engineered for high-performance electromagnetic interference suppression in modern electronics. The series emphasizes small form factors combined with robust electrical characteristics. They serve as critical passive elements in maintaining signal integrity and regulatory compliance in dense circuit boards.

Replacement Considerations

Cross-reference with other SBSMC series variants for different capacitance or voltage ratings. Verify pinout and footprint compatibility with existing board layouts. Ensure thermal and electrical specifications meet or exceed original design parameters when substituting.
