Overview
The TDK YFF21PC1E473M is a surface-mount EMI feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 0.047 µF with a voltage rating of 25 V and a tolerance of ±20%. The component utilizes C0G dielectric material to ensure stable performance across varying temperatures. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards. The device is housed in an 0805 (2012 Metric) package, measuring 2.0 mm in length, 1.25 mm in width, and 1.00 mm in maximum height.
Feature Summary
- Provides effective electromagnetic interference suppression through three-terminal feedthrough architecture
- Maintains capacitance stability over wide temperature variations using C0G dielectric technology
- Complies with AEC-Q200 automotive reliability standards for harsh environment operation
Applications
- Power supply input filtering
- Battery charger circuit protection
- Voltage regulation stage noise attenuation
Procurement Notes
Verify the specific suffix codes against official TDK documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with standard reflow soldering profiles for surface-mount assembly. Confirm that the selected variant meets all required automotive or industrial qualification standards before integration into final designs.
Selection Notes
Select this component when compact footprint and high capacitance density are required for EMI filtering. The 0805 package size suits space-constrained layouts. Verify that the 25 V rating exceeds the maximum circuit voltage including transients. Consider the thermal operating range limits if deployed in high-temperature environments.
Part Context
This part belongs to the TDK YFF-P series of feedthrough capacitors. These components are engineered for efficient power conversion and voltage regulation applications. The series offers a balance of small physical dimensions and robust noise suppression capabilities suitable for modern electronic systems.
Replacement Considerations
Cross-reference with other TDK YFF-P series variants such as YFF21AC1H470MT0Y0N for different capacitance values. Ensure any substitute maintains identical package dimensions and AEC-Q200 certification if automotive use is required.
