Overview
The NFA31GD1001014D is a surface-mount RC EMI filter circuit from Murata Electronics, housed in a 1206 (3216 Metric) package. It features four channels with a bus topology configuration. Each channel integrates a 10 pF capacitor with ±20% tolerance and a 100 Ohm resistor with ±30% tolerance. The device has a rated voltage of 6 V DC and a maximum DC resistance of 100 Ohms. It operates within a temperature range of -40°C to +85°C and supports a current rating of 15 mA.
Feature Summary
- Integrates four independent RC filter channels within a single compact surface-mount package
- Utilizes a bus topology design for efficient signal line protection
- Provides low-pass filtering characteristics to suppress electromagnetic interference
Applications
- General purpose EMI suppression in electronic circuits
- Signal line protection for data interfaces
- Noise filtering in portable consumer devices
Procurement Notes
Verify the specific suffix GD against official Murata documentation to confirm the exact component values and tolerance levels. Ensure the 1206 footprint matches the target PCB layout dimensions. Confirm that the 6V rated voltage meets the operational requirements of the application circuit. Check for RoHS compliance status if required by regulatory standards.
Selection Notes
Select this component when space constraints require a multi-channel filter solution in a 1206 package. Consider the 100 Ohm resistance and 10 pF capacitance values for appropriate cutoff frequency requirements. Evaluate the 15 mA current rating to ensure it exceeds the maximum expected signal current. Verify compatibility with surface-mount assembly processes.
Part Context
This part belongs to the NFA31 series of EMI/RFI suppressors manufactured by Murata. The series offers various configurations for noise suppression in compact electronics. The NFA31GD variant specifically provides a four-channel RC filter structure designed for general-purpose applications requiring moderate filtering performance in small form factors.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult Murata's official cross-reference tools or datasheets for potential alternatives.
