YFF31PC1C104MT000N

Overview

The YFF31PC1C104MT000N is a surface-mount feedthrough capacitor from the TDK YFF-P series. It features a capacitance of 0.1 µF with a ±20% tolerance and a rated voltage of 16V DC. The component supports a maximum current of 2 A and has a maximum DC resistance of 40 mΩ. Housed in a 1206 (3216 Metric) package with four terminals, it measures 3.20mm x 1.60mm x 1.45mm. It provides insertion loss of 40dB between 7MHz and 1GHz and operates within a temperature range of -55°C to 125°C.

Feature Summary

• Integrates high capacitance density within a compact 1206 surface-mount footprint for efficient PCB space utilization.
• Provides effective electromagnetic interference suppression through low impedance characteristics at high frequencies.
• Features a robust ceramic construction designed for stable performance across wide industrial temperature ranges.

Applications

• Power supply input filtering for portable electronic devices
• Noise suppression on data lines in mobile communication equipment
• EMI reduction in automotive infotainment systems

Procurement Notes

Verify the specific suffix codes against the official TDK datasheet to ensure compatibility with required termination materials and moisture sensitivity levels. Confirm that the 1206 package dimensions align with the target PCB land pattern. Check for any recent Product Change Notices regarding material updates or manufacturing site changes. Ensure storage conditions meet the specified humidity sensitivity等级 requirements before reflow soldering.

Selection Notes

Select this component when a balance of moderate current handling and high capacitance is required in a standard 1206 footprint. Compare the 40mΩ DCR against circuit power loss constraints. Evaluate the 16V rating against peak transient voltages in the application. Consider the YFF-HC series if higher current ratings or lower resistance are necessary for similar form factors.

Part Context

This part belongs to the TDK YFF-P series of feedthrough capacitors, which utilize a unique internal structure to minimize parasitic inductance. The series is designed to replace traditional discrete LC filters by combining filtering and decoupling functions into a single surface-mount device. The YFF31 designation indicates the specific case size and terminal configuration within this product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult TDK's official replacement guides or contact technical support for qualified alternatives, as direct pin-to-pin replacements may require verification of electrical parameters and mechanical tolerances.
