VFS6045SA151

Overview

The VFS6045SA151 is a single-line noise suppression filter manufactured by TDK Corporation, belonging to the VFS series. It features a surface-mount design with dimensions of 6.00 mm in length, 6.00 mm in width, and a maximum height of 4.50 mm. The component provides an impedance of 188 Ohms at 1 MHz and supports a maximum DC current of 1.5 A. Its maximum DC resistance is specified as 175 mOhms. The device operates within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Feature Summary

• Provides effective noise suppression for single power lines through high-impedance characteristics at target frequencies.
• Features a compact surface-mount footprint suitable for space-constrained printed circuit board layouts.
• Capable of handling significant direct current loads while maintaining low DC resistance to minimize power loss.

Applications

• Noise filtering on single power supply rails in electronic circuits
• Signal integrity enhancement in portable consumer devices
• Electromagnetic interference reduction in industrial control systems

Procurement Notes

Verify the specific impedance value against the latest official datasheet, as distributor listings may vary between 175 Ohms and 188 Ohms. Confirm the package type is SMD/SMT and check for RoHS3 compliance requirements. Ensure the maximum DC current rating of 1.5 A meets the application's thermal and electrical constraints before finalizing procurement.

Selection Notes

Select this component when a single-line ferrite bead is required for power rail noise suppression. The 6x6 mm package offers a balance between current handling capacity and board space efficiency. Consider the 188 Ohm impedance at 1 MHz to ensure it aligns with the frequency spectrum of the noise being suppressed. Verify that the 1.5 A current rating exceeds the maximum operating current of the protected line.

Part Context

This part belongs to the TDK VFS series of noise suppression filters, designed for general-purpose electromagnetic interference mitigation. The series includes various impedance values and current ratings within standardized surface-mount packages. The VFS6045SA151 specifically targets applications requiring moderate current handling with a 6x6 mm footprint.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other VFS series components from TDK or equivalent ferrite beads from other manufacturers based on matching impedance, current rating, and physical dimensions.
