SF200-28-28S-B-H

Overview

The SF200-28-28S-B-H is an EMI filter component manufactured by Microchip Technology, designed for through-hole mounting. It features a single output configuration with a maximum input voltage of 28V. The device exhibits a channel resistance of 0.025 Ohms and has a physical height of 12.70mm (0.500 inches). It operates within standard industrial temperature ranges and complies with REACH regulations, ensuring environmental safety for electronic assemblies requiring noise suppression.

Feature Summary

• Provides effective electromagnetic interference filtering for sensitive circuits
• Supports single-output configurations with low channel resistance
• Designed for reliable through-hole installation on printed circuit boards

Applications

• Power supply input stages requiring noise attenuation
• Industrial control systems needing signal integrity protection
• Automotive electronics utilizing 28V nominal systems

Procurement Notes

Verify the specific suffix B-H against official Microchip documentation to confirm exact electrical characteristics and mechanical dimensions. Ensure compatibility with existing board layouts regarding through-hole spacing and height constraints. Cross-reference datasheets for thermal performance limits under expected load conditions before finalizing procurement specifications.

Selection Notes

Select this component when low insertion loss and high current handling are required in a compact through-hole package. Compare channel resistance values against alternative filters to ensure minimal voltage drop. Confirm that the 28V input rating aligns with the system's maximum operating voltage to prevent component failure during transient events or steady-state operation.

Part Context

This part belongs to the SF200 series of EMI/RFI filters from Microchip Technology. These components are engineered to suppress high-frequency noise in power lines. The series offers various input/output configurations and resistance values to suit different application requirements while maintaining consistent form factors for easy integration into existing designs.

Replacement Considerations

Direct substitutes must match the 28V input rating, single-output topology, and approximately 0.025 Ohm channel resistance. Verify mechanical footprint compatibility for through-hole mounting. Check if alternative manufacturers offer equivalent filtering performance within the same physical envelope.
