Overview
The NFL21SP206X1C7D is a third-order low-pass LC Pi filter from Murata Electronics, designed for electromagnetic interference suppression. It features an inductance of 700 nH and capacitance of 240 pF, with a cutoff frequency of 20 MHz. Rated for 16 V and 100 mA, this component utilizes a surface-mount 0805 package measuring 2.00 mm x 1.25 mm x 0.95 mm. It operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.
Feature Summary
- Third-order LC Pi topology for enhanced high-frequency noise attenuation
- Compact 0805 surface-mount footprint for space-constrained designs
- Wide operating temperature range suitable for harsh environments
Applications
- General-purpose EMI suppression in electronic circuits
- Signal line filtering in portable devices
- Power rail noise reduction in consumer electronics
Procurement Notes
Verify current availability status as the part is listed as obsolete or end-of-life by major distributors. Confirm final assembly compatibility with existing PCB footprints before procurement planning. Check for official replacement recommendations from Murata Electronics to ensure long-term supply chain stability and design continuity.
Selection Notes
Select this component when specific attenuation characteristics at 20 MHz are required alongside compact size constraints. The 100 mA current rating limits suitability for high-power applications. Ensure circuit impedance matches the filter's design parameters for optimal performance. Consider thermal management requirements given the wide operational temperature range.
Part Context
This component belongs to the EMIFIL NFL21 series, which offers multilayer ceramic EMI suppression filters in various configurations. The NFL21SP variant specifically provides Pi-filter structures in standard SMD packages. This series is engineered for reliable noise reduction in digital and analog signal lines across consumer and industrial sectors.
Replacement Considerations
Consult Murata Electronics for officially confirmed substitute part numbers due to the product's obsolete status. Verify electrical equivalence and physical dimensions if considering alternative suppliers. Do not assume cross-compatibility without manufacturer validation.
