VFS6VD81E221T51B

Overview

The Murata Electronics VFS6VD81E221T51B is a third-order LC (T-type) EMI suppression filter designed for signal line surge protection. It features a rated voltage of 25V and a current rating of 6A, with an integrated capacitance of 220pF. The component utilizes a 3-SIP through-hole package, measuring approximately 14.5mm in length, 7.0mm in width, and 9.0mm in height. It operates within a temperature range of -40°C to +105°C and is RoHS compliant.

Feature Summary

• Provides third-order low-pass filtering for effective EMI noise suppression
• Integrates surge protection against static electricity and transient events
• Supports high current handling up to 6A in a compact form factor

Applications

• Surge protection for sensitive signal lines
• EMI/RFI filtering in communication equipment
• Noise suppression in automotive electronic circuits

Procurement Notes

Verify the specific suffix 'T51B' to ensure correct packaging and terminal configuration. Confirm that the 25VDC rating and 6A current capacity align with the target circuit requirements. Check for end-of-life status or alternative sourcing options as availability may vary by region.

Selection Notes

Select this component when a combined solution for EMI filtering and surge protection is required on low-voltage signal lines. The T-type LC topology offers superior attenuation compared to single-stage filters. Ensure the physical footprint fits the available PCB space for the 3-SIP package.

Part Context

This part belongs to the Murata VFS6V series, which specializes in compact EMI suppression filters for signal lines. The series is engineered to protect circuits from electrostatic discharge and electromagnetic interference while maintaining signal integrity in data transmission applications.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate generic 3rd-order LC filters with matching 25V/6A ratings if exact replacement is unavailable.
