SBSMC1000334MXB

Overview

The Knowles Syfer SBSMC1000334MXB is a surface-mount EMI filter circuit designed for high-frequency noise suppression. It features a C-filter topology with a capacitance of 0.33 µF and a voltage rating of 100 VDC. The component utilizes X7R dielectric material with a ±20% tolerance, housed in a compact 6.6 x 5 mm package. Operating within a temperature range of -55°C to +125°C, it provides reliable performance for signal integrity applications.

Feature Summary

• Integrates a C-filter topology for effective electromagnetic interference suppression
• Utilizes X7R ceramic dielectric for stable capacitance across operating temperatures
• Features a compact surface-mount footprint optimized for dense PCB layouts

Applications

• High-speed digital signal line filtering
• Power supply decoupling in noisy environments
• RF circuit noise attenuation

Procurement Notes

Verify the specific package dimensions and termination compatibility against your PCB footprint before ordering. Confirm that the X7R dielectric characteristics meet your application's stability requirements under varying thermal conditions. Ensure the 100V DC rating exceeds the maximum operational voltage including transients. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a single-capacitor C-filter solution is preferred over complex RC or LC networks. Consider the X7R dielectric properties regarding voltage coefficient and temperature stability compared to C0G/NP0 types. Evaluate the physical size constraints against the available board space. Compare leakage current specifications if used in precision analog circuits.
