YFF18PH0J225MT000N

Overview

The TDK YFF18PH0J225MT000N is a surface-mount EMI feedthrough capacitor from the YFF-P series. It features a capacitance of 2.2 µF with ±20% tolerance and an X5R dielectric. Rated for 6.3 V DC, it supports a maximum current of 4 A and has a maximum DC resistance of 12 mΩ. The component operates between -55°C and +85°C. Its physical dimensions are 1.6 mm x 0.8 mm x 0.9 mm (0603 metric package). Insertion loss is specified as 40 dB across the 400 kHz to 1 GHz frequency range.

Feature Summary

• Provides high capacitance in a compact 0603 footprint for efficient PCB layout
• Designed specifically for power line filtering applications
• Offers low impedance characteristics suitable for high-current environments

Applications

• Power line filtering in electronic circuits
• EMI suppression for high-density surface mount designs
• Commercial grade electronic equipment

Procurement Notes

Verify the specific suffix 'T000N' against official TDK documentation to confirm packaging configuration and RoHS compliance status. Ensure the voltage rating of 6.3V aligns with circuit requirements. Confirm that the 4A current handling capability meets the application's peak load demands before finalizing procurement.

Selection Notes

Select this component when space constraints require a 0603 package but high capacitance is necessary. The 6.3V rating limits suitability for higher voltage rails. Consider the 4A current limit for power integrity. The X5R temperature coefficient provides stable performance within the specified operating range for commercial applications.

Part Context

This part belongs to the TDK YFF-P series of three-terminal feedthrough capacitors. These components integrate filtering functionality directly into the capacitor structure, reducing parasitic inductance compared to standard MLCCs. The series is designed to replace discrete filter components, simplifying circuit design and improving high-frequency noise attenuation efficiency.

Replacement Considerations

Check for direct substitutes within the YFF-P series with identical 0603 dimensions and 2.2µF capacitance. Verify that any replacement maintains the 6.3V rating and 4A current capacity. Ensure the new part supports the required insertion loss specifications for the target frequency band.
