• Compact 0603 surface-mount form factor

Applications

• General-purpose signal line EMI suppression
• High-frequency noise reduction in electronic circuits

Procurement Notes

This component is officially classified as obsolete and has been discontinued by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the production lot date and physical condition prior to acquisition, as availability is limited and supply chain support is no longer active.

Selection Notes

Engineers requiring this specific electrical profile should evaluate alternative components from the same series that remain in active production. Selection criteria must prioritize matching the 62nH inductance, 18pF capacitance, and 300MHz cutoff frequency while ensuring compatibility with the 0603 footprint and 16V/200mA ratings to maintain circuit integrity during design updates.

Part Context

The NFL18ST307X1C3D belongs to the EMIFIL NFL18 series, which specializes in compact EMI suppression filters for signal lines. This series is designed for applications requiring effective noise attenuation in space-constrained environments. The part utilizes a T-type LC network structure to provide superior filtering performance compared to standard single-stage filters.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the product's discontinued status.
