Feature Summary

• Integrates T-type circuit topology combining capacitive filtering with ferrite bead inductance for enhanced high-frequency noise attenuation.
• Provides robust electromagnetic interference (EMI) and radio frequency interference (RFI) suppression through feed-through architecture.
• Meets automotive reliability standards via AEC-Q200 qualification for use in demanding electronic environments.

Applications

• Automotive electronics systems requiring certified EMI filtering components
• High-speed digital signal lines needing combined capacitive and inductive noise reduction
• Power supply input/output stages for broadband interference suppression

Procurement Notes

Verify the specific suffix codes against official Murata documentation to ensure exact electrical characteristics and packaging details match project requirements. Confirm availability status directly with authorized distributors as stock levels fluctuate. Ensure compliance with RoHS directives and AEC-Q200 automotive grade specifications before finalizing procurement orders for production integration.

Selection Notes

Select this component when a compact solution is needed for simultaneous capacitive bypassing and inductive isolation in tight spaces. The 3-terminal feed-through design offers superior high-frequency performance compared to standard surface-mount capacitors. Consider the 50V DC rating and 220pF value for compatibility with low-voltage signal integrity applications requiring minimal parasitic effects.

Part Context

This part belongs to the Murata NFE series of feed-through capacitors, which are specialized filters designed for effective EMI/RFI suppression in small form factors. The series is widely utilized in automotive and industrial applications where space constraints and high-performance noise filtering are critical requirements for system reliability and regulatory compliance.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate alternative NFE series variants or similar T-type feed-through capacitors only after verifying identical electrical parameters, package dimensions, and AEC-Q200 qualification status to ensure functional equivalence.
