YFF32SC1E470M

Overview

The TDK YFF32SC1E470M is a surface-mount EMI feedthrough filter capacitor in the CKD series. It features a three-terminal design with a capacitance of 47 pF and a rated voltage of 25 V DC. The component utilizes C0G dielectric material for stability and is housed in a 1206 (3216 metric) package. Key electrical characteristics include a maximum DC resistance of 600 mOhms and a current rating of 200 mA. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal architecture designed to minimize equivalent series inductance (ESL).
• Utilizes C0G dielectric material for consistent performance across temperature variations.
• Surface-mount construction optimized for high-frequency electromagnetic interference suppression.

Applications

• High-speed digital signal line filtering in consumer electronics.
• EMI suppression in portable communication devices.
• Noise reduction in compact embedded systems requiring low-profile components.

Procurement Notes

Verify the specific suffix and tolerance requirements against your schematic, as the CKD series may have variants. Confirm RoHS compliance status if required by your manufacturing standards. Ensure the 1206 footprint matches your PCB layout constraints. Check for any recent lifecycle notices regarding this specific part number before finalizing procurement plans.

Selection Notes

Select this component when low ESL is critical for high-frequency noise attenuation. The 47 pF value suits signal lines where minimal capacitance loading is necessary. The 25 V rating provides adequate margin for low-voltage logic circuits. Consider the 600 mOhm resistance limit for current-carrying capacity requirements in the target application path.

Part Context

This part belongs to TDK's CKD series of feedthrough capacitors, which are engineered for superior high-frequency performance compared to standard MLCCs. The series is characterized by its unique internal structure that reduces parasitic inductance, making it suitable for applications where traditional capacitors fail to suppress broadband noise effectively.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers' 1206 feedthrough filters only after confirming identical pinout, capacitance tolerance, and voltage ratings.
