Overview
The YFF18AC1H222MT0Y0N is a surface-mount EMI feedthrough capacitor manufactured by TDK Corporation. It features a capacitance of 2200 pF with a tolerance of ±20% and a rated voltage of 50 V DC. The component utilizes X7S dielectric material and is housed in an 0603 (1608 metric) package, measuring 1.60 mm in length and 0.80 mm in width. Designed for automotive applications, it holds AEC-Q200 qualification. The device supports a maximum DC current of 1 A and includes a ground terminal for effective noise suppression.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- Integrated ground terminal for enhanced EMI suppression
- Surface-mount construction for automated assembly
Applications
- Automotive power supply circuits
- Battery charger input filtering
- Portable electronic device noise suppression
Procurement Notes
Verify the specific suffix codes against official TDK documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the AEC-Q200 qualification status aligns with your target application's regulatory requirements. Cross-reference the 0603 footprint dimensions with your PCB layout guidelines to ensure mechanical compatibility during procurement.
Selection Notes
Select this component when a compact 0603 form factor is required for high-frequency noise attenuation in automotive or industrial environments. The 50 V rating and 1 A current capacity suit low-voltage DC line filtering. Ensure the X7S temperature stability meets the operational thermal range of the target circuit design before finalizing the selection.
Part Context
This part belongs to the TDK YFF series of feedthrough capacitors, which integrate a third terminal for improved high-frequency performance compared to standard two-terminal designs. The series is engineered for electromagnetic interference suppression in space-constrained printed circuit boards, offering a balance between electrical performance and miniaturization for modern electronic systems.
Replacement Considerations
The YFF21AC1H222MT0Y0N serves as a verified alternative within the same product family. It shares identical electrical parameters but utilizes an 0805 package, requiring appropriate footprint adaptation during substitution.
