YFF31AH2A105MT0Y0N

Overview

The YFF31AH2A105MT0Y0N is a three-terminal EMI feedthrough filter capacitor manufactured by TDK Corporation. It features a capacitance of 1 µF with a tolerance of ±20% and an X7S dielectric material. The component has a rated DC voltage of 100V and supports a continuous current of 6 A at 105°C, or 4 A at 125°C. It operates within a temperature range of -55°C to +125°C. The device is housed in a 1206 (3216 Metric) surface-mount package with four pads and complies with the AEC-Q200 automotive qualification standard.

Feature Summary

• Three-terminal structure for effective high-frequency noise suppression
• Automotive-grade reliability compliant with AEC-Q200 standards
• High current handling capability suitable for power line applications

Applications

• Large-current power lines in automotive systems
• EMI filtering for automotive electronic control units
• Noise suppression in vehicle power distribution networks

Procurement Notes

Verify that the specific suffix MT0Y0N matches the required packaging and tape-and-reel specifications for your assembly line. Confirm the AEC-Q200 certification status if automotive compliance is mandatory for your design. Ensure the 1206 footprint aligns with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when high capacitance and current handling are required in a compact surface-mount form factor. The X7S dielectric offers stable performance across the specified temperature range. Consider the three-terminal design for superior high-frequency attenuation compared to standard two-terminal capacitors in noisy environments.

Part Context

This part belongs to the YFF-AH series of three-terminal filters designed specifically for automotive large-current power lines. The series provides robust EMI suppression capabilities while maintaining low impedance characteristics. The YFF31AH2A105MT0Y0N represents a specific configuration within this family, optimized for 100V applications.

Replacement Considerations

Check for direct substitutes within the YFF series with identical capacitance and voltage ratings. Verify that any alternative maintains the same three-terminal architecture and AEC-Q200 qualification. Ensure the replacement part fits the 1206 footprint and meets the 6 A current requirement.
