Procurement Notes

Verify the complete part number including the suffix MT009N to ensure correct packaging configuration. Confirm that the 0805 footprint matches the target PCB layout dimensions. Check the datasheet for specific reflow soldering profiles compatible with the component's thermal characteristics. Ensure the 50V DC rating meets the operational voltage requirements of the signal lines.

Selection Notes

Select this component when high-frequency noise attenuation is required on signal lines within limited board space. The three-terminal structure offers superior performance compared to standard two-terminal capacitors at higher frequencies. Consider the 100 pF value and 50V rating to match the specific signal integrity needs. The wide operating temperature range ensures reliability across various environmental conditions.

Part Context

This component belongs to TDK's YFF series of three-terminal feed-through capacitors. These components are engineered specifically for suppressing electromagnetic interference in high-speed digital and analog circuits. The series provides a balance between small size and effective noise filtration, making them suitable for modern consumer electronics and industrial control systems requiring robust signal integrity.

Replacement Considerations

Check for equivalent three-terminal feed-through capacitors from other manufacturers with matching 100 pF capacitance, 50V rating, and 0805 footprint. Verify that any substitute maintains similar high-frequency impedance characteristics and thermal stability. Ensure the replacement component complies with the same safety and environmental regulations.
