VFS5045VA031

Overview

The VFS5045VA031 is a single-line ferrite bead from the TDK VFS series, designed for power line noise suppression. It features a 2020 (5050 metric) surface-mount package with dimensions of 5.00mm length and 0.50mm height. The component exhibits an impedance of 61 Ohms at 10 MHz and a maximum DC resistance of 19.5 milliohms. It supports a rated current of 5.1A and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Provides conductive noise suppression for power lines
• Engineered for high-current applications up to 5.1A
• Compact 2020 surface-mount footprint

Applications

• Home appliances
• Power supply input filtering
• Noise suppression in compact electronic devices

Procurement Notes

Verify the specific suffix VA031 against the official TDK datasheet to confirm packaging type and tape/reel specifications. Ensure the selected variant matches the required 2020 package dimensions and 5.1A current rating for your circuit design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when space constraints require a 2020 package size while maintaining high current handling capabilities. The 61 Ohm impedance at 10 MHz makes it suitable for suppressing common switching frequencies in power lines. Verify that the 19.5 milliohm DC resistance meets the voltage drop requirements of the target application.

Part Context

This ferrite bead belongs to the TDK VFS series, which focuses on high-performance noise suppression for power circuits. The VFS5045VA031 specifically utilizes a monolithic structure to provide effective attenuation in a small form factor. It is intended for use in environments requiring reliable EMI reduction without significant signal degradation.

Replacement Considerations

Consult the official TDK VFS series replacement guide for direct substitutes. Ensure any alternative maintains the 2020 package outline and 5.1A current rating.
