Overview
The Murata NFE61HT681D2A9L is a three-terminal feedthrough capacitor designed for surface mount applications. It features a capacitance of 680 pF with a tolerance of 30% and a DC voltage rating of 100 VDC. The component supports a rated current of 2 A and operates within a temperature range of -55°C to +125°C. Its physical dimensions are 6.8 mm in length, 1.6 mm in width, and 1.6 mm in height, housed in a 2606 package. The device meets AEC-Q200 automotive qualification standards and offers an insulation resistance of 1 GOhms.
Feature Summary
- Combines feedthrough capacitor and ferrite bead functions in a single LC combined type structure
- Provides high current handling capability of 2 A with low voltage drop due to small DC resistance
- Suitable for DC power line noise suppression applications
- Automotive qualified under AEC-Q200 standards
Applications
- Automotive electronics DC power lines
- EMI/RFI noise suppression in automotive circuits
- Power supply filtering for high-current DC applications
Procurement Notes
Verify the specific suffix D2A9L against official Murata documentation to confirm packaging configuration and tape/reel specifications. Ensure compatibility with SMD/SMT assembly processes given the 2606 package size. Confirm that the 100V DC rating and 2A current capacity meet the target circuit requirements before procurement.
Selection Notes
Select this component when high current handling and compact footprint are required for EMI filtering. The 680 pF capacitance value is suitable for specific frequency attenuation needs. Verify that the 100V DC rating exceeds the maximum operating voltage of the application. Consider the AEC-Q200 qualification if the design targets automotive reliability standards.
Part Context
This part belongs to the Murata NFE series of EMIFIL components. These are chip-type EMI filters combining LC characteristics. The series offers various capacitance values from 22pF to 4700pF. The NFE61HT variant specifically addresses high-current DC power line applications in automotive environments.
Replacement Considerations
Check Murata's official substitution guide for equivalent parts within the NFE series. Verify pinout compatibility and electrical parameters such as capacitance, voltage rating, and current handling. Ensure any substitute also meets AEC-Q200 requirements if used in automotive contexts.
