SBSMP5000103MXT

Overview

The Knowles Syfer SBSMP5000103MXT is a surface-mount EMI network filter circuit designed for high-frequency noise suppression. It features a Pi filter topology with a capacitance of 0.01 µF (10 nF) and a voltage rating of 500 V DC. The component utilizes X7R dielectric material, providing stable performance across an operating temperature range of -55°C to +125°C. With a tolerance of ±20% and a current rating of 10 A, it offers significant attenuation of 44 dB. The device is housed in a compact 6.6 mm x 5 mm package with a maximum height of 3.18 mm, suitable for space-constrained PCB layouts.

Feature Summary

• Integrates a Pi filter topology within a single surface-mount component for efficient EMI suppression
• Provides high voltage insulation capability rated at 500 V DC
• Delivers substantial signal attenuation of 44 dB for effective noise reduction
• Supports high continuous current handling up to 10 A

Applications

• High-voltage power supply input filtering
• EMI suppression in industrial control systems
• Noise filtering for motor drive circuits
• Signal integrity protection in automotive electronics

Procurement Notes

Verify the specific datasheet revision when sourcing, as manufacturer specifications may undergo updates. Confirm that the 500 V DC rating aligns with your system's peak voltage requirements. Ensure the 10 A current rating exceeds the maximum operational load to prevent thermal failure. Check compatibility with standard SMT reflow profiles for the specified package dimensions.

Selection Notes

Select this component when integrated EMI filtering is required alongside high voltage isolation. The Pi filter configuration simplifies design by replacing multiple discrete components. Consider the 6.6 mm x 5 mm footprint for board space constraints. Verify that the X7R temperature coefficient meets the environmental stability needs of the application.

Part Context

This part belongs to the Knowles Syfer SBSMP series of EMI network filters. These components are engineered to replace traditional discrete LC filters, offering reduced board area and improved reliability. The series targets applications requiring robust noise suppression in harsh electrical environments.

Replacement Considerations

Direct substitutes must match the 500 V rating, 0.01 µF capacitance, and Pi filter topology. Verify that alternative components maintain the 10 A current rating and 44 dB attenuation level. Ensure physical dimensions fit the existing PCB layout without modification.
