Overview
The TDK YFF18PC0J475MT0H0N is a three-terminal EMI feedthrough filter capacitor in a 0603 (1.6mm x 0.8mm) surface-mount package. It features a capacitance of 4.7 µF with ±20% tolerance and a rated DC voltage of 6.3V. The component supports a maximum current rating of 4A and exhibits a maximum DC resistance of 12 mΩ. It operates within a temperature range of -55°C to +85°C and provides an insertion loss of 40dB from 200kHz to 1GHz.
Feature Summary
- Three-terminal feedthrough architecture for effective power line filtering
- High capacitance density in compact 0603 footprint
- Low impedance characteristics suitable for high-current applications
Applications
- Power supply input filtering
- DC-DC converter output stages
- Noise suppression on high-speed digital lines
Procurement Notes
Verify the specific suffix 'PC' against project requirements, as it denotes a particular series variant within the YFF family. Confirm RoHS compliance status via the latest manufacturer datasheet before finalizing procurement. Ensure the selected packaging format matches assembly line capabilities. Cross-reference the part number with official TDK documentation to confirm current production status and availability constraints.
Selection Notes
Select this component when space-constrained designs require high capacitance values alongside significant current handling capabilities. The 0603 package allows for dense PCB layouts while maintaining low parasitic inductance. Consider the 6.3V rating relative to peak voltage transients in the target circuit. Evaluate the 4A current rating against steady-state load requirements to ensure reliable operation without excessive self-heating.
Part Context
This component belongs to the TDK YFF-PW or YFF-P series of electromagnetic interference feedthrough filters. These devices are engineered to replace standard MLCCs in power paths, offering superior noise attenuation due to their internal grounding structure. The series is designed for modern electronics requiring efficient EMI suppression in minimal board space.
Replacement Considerations
Direct substitutes include other TDK YFF series parts with identical 0603 dimensions and similar electrical parameters. Verify pinout compatibility and thermal performance when considering alternatives from different manufacturers.
