Overview
The NFA18SD207X1A45L is a four-channel LC EMI filter array manufactured by Murata Electronics. It operates with a cutoff frequency of 200 MHz and provides 15 dB attenuation. The component supports a maximum current rating of 25 mA and a voltage rating of 10 V. It utilizes an SMD/SMT termination type within a compact 0603 (1608 metric) package. The device functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Four-channel configuration for multi-line signal filtering
- LC circuit topology for effective noise suppression
- Compact surface-mount design suitable for space-constrained layouts
Applications
- General purpose EMI/RFI filtering
- Signal line protection in consumer electronics
- Data bus noise reduction in portable devices
Procurement Notes
Verify the lifecycle status before procurement, as this component is marked as Not Recommended for New Designs (NRND). Confirm that existing inventory or last-time buy options align with long-term production requirements. Ensure compatibility with standard reflow soldering profiles for the specified 0603 package dimensions.
Selection Notes
Select this component when a low-profile, multi-channel solution is required for high-frequency noise suppression. The 200 MHz cutoff frequency makes it suitable for protecting sensitive digital interfaces. Consider the 25 mA current limit to ensure it matches the operational load of the target circuit without exceeding ratings.
Part Context
This part belongs to the Murata EMIFIL NFA18SD series, which focuses on compact EMI suppression for portable applications. The series utilizes thin-film technology to achieve high performance in small footprints. It is designed to meet RoHS compliance standards and SVHC regulations for environmental safety.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components from the same manufacturer or other vendors should be evaluated based on identical electrical parameters and package dimensions.
