Overview
The YFF15PC0G435MT000N is a three-terminal feedthrough capacitor from TDK's YFF-P series, designed for surface-mount applications in the 0402 (1005 metric) package. It features a capacitance of 4.3 µF with ±20% tolerance and a C0G dielectric. The component has a rated voltage of 4V DC, a maximum DC resistance of 30 mΩ, and supports a continuous current of 2 A. Operating temperature ranges from -55°C to +105°C.
Feature Summary
- Three-terminal feedthrough architecture provides effective electromagnetic interference suppression for signal and power lines.
- C0G ceramic dielectric ensures stable capacitance characteristics across varying temperatures and voltages.
- Compact 0402 surface-mount footprint facilitates high-density PCB layouts.
Applications
- Power line filtering in portable electronic devices
- Signal line noise suppression in mobile communications equipment
- Electromagnetic interference mitigation in compact consumer electronics
Procurement Notes
Verify the specific suffix MT000N against the manufacturer's latest datasheet to confirm packaging and tape/reel specifications. Ensure compatibility with standard reflow soldering profiles for 0402 components. Cross-reference RoHS compliance status directly with TDK documentation prior to procurement.
Selection Notes
Select this component when low-voltage operation near 4V is required alongside high capacitance in a minimal footprint. The C0G dielectric is suitable for applications demanding precise capacitance stability. Evaluate the 2A current rating against circuit load requirements to ensure adequate thermal performance within the specified temperature range.
Part Context
This part belongs to the YFF-P series of high-capacitance feedthrough filters. It complements other YFF-SC models by offering higher capacitance values in the same 0402 form factor. The series targets modern miniaturized electronics requiring robust EMI filtering without increasing board space.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult TDK technical support or official distributor catalogs for direct equivalents.
