Overview
The NFM18PS105R0J3D is a feedthrough capacitor from the Murata EMIFIL NFM18 series, designed for large current applications. It features a capacitance of 1 µF with a ±20% tolerance and a rated voltage of 6.3V. The component supports a maximum current of 2 A and has a maximum DC resistance (DCR) of 30 mΩ. It utilizes a surface-mount 0603 (1608 Metric) package with three PCB pads. The operating temperature range spans from -55°C to 105°C.
Feature Summary
- Feedthrough design providing low impedance paths for high-frequency noise suppression
- Capable of handling large currents up to 2 A with minimal resistive loss
- Compact 0603 surface-mount footprint suitable for space-constrained layouts
Applications
- Power supply input filtering in compact electronic devices
- Noise suppression on high-current signal lines
- EMI reduction in automotive comfort systems
Procurement Notes
Verify the specific suffix 'R0' against official datasheets to confirm the 105°C temperature rating, as similar part numbers may differ. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Confirm that the 0603 package dimensions align with your PCB land pattern specifications before finalizing procurement.
Selection Notes
Select this component when high capacitance density is required in a small surface-mount package. The 2 A current rating makes it suitable for power rails where standard capacitors might fail due to thermal limits. Consider the 30 mΩ DCR impact on voltage drop in high-current paths during circuit design.
Part Context
This component belongs to the Murata EMIFIL NFM18 series, which specializes in feedthrough capacitors for large current applications. The series offers various capacitance values and voltage ratings within the 0603 form factor, balancing performance with board space efficiency for modern electronics.
Replacement Considerations
NFM18PS105D0J3D shares identical electrical parameters but differs in temperature rating (125°C vs 105°C). Verify thermal requirements before substitution.
