Overview
The NFL21SP207X1C3D is a Murata EMIFIL EMI filter circuit in the NFL21SP series. It utilizes an LC (Pi) topology configured as a third-order low-pass filter with one channel. The component features an inductance of 72 nH and capacitance of 22 pF, rated for 250 mA current and 16 VDC voltage. It is housed in a compact 0805 (2012 metric) SMD package with dimensions of 2 mm x 1.25 mm x 0.85 mm. Operating temperatures range from -55°C to +125°C.
Feature Summary
- Integrates LC Pi-filter topology for third-order low-pass signal attenuation
- Utilizes multilayer construction within a standard 0805 surface-mount footprint
- Designed for high-temperature stability across extended industrial ranges
Applications
- High-speed data line EMI suppression
- Signal integrity protection in portable electronics
- Noise filtering in automotive infotainment systems
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeits. Confirm RoHS compliance status via official documentation. Check end-of-life status as this specific part may be discontinued or subject to limited availability. Ensure storage conditions align with manufacturer guidelines for moisture sensitivity levels prior to assembly.
Selection Notes
Select this component when a third-order low-pass response is required in a minimal 0805 footprint. Compare against similar NFL21SP variants if different cutoff frequencies or current ratings are needed. Verify that the 250 mA rating meets the application's peak current demands without saturation. Ensure the 16 VDC rating exceeds the maximum operating voltage of the protected circuit.
Part Context
This part belongs to the Murata NFL21SP series, which offers multilayer EMI filters in small surface-mount packages. The series provides integrated solutions for noise suppression where discrete components would consume excessive board space. These filters are designed to replace multiple passive components with a single reliable unit.
Replacement Considerations
NFL21SP206X1C7D is a related variant within the same series but differs in electrical specifications. Verify compatibility before substitution as parameter changes may affect filter performance.
