FL450K0000S0A1

Overview

The FL450K0000S0A1 is a surface-mount ceramic filter manufactured by NextGen Components. It operates at a center frequency of 450kHz, designed for AM signal processing applications. The component features a 3-SMD J-Lead package with dimensions of 6.5mm length, 6.0mm width, and 4.2mm height. Key electrical specifications include a maximum insertion loss of 4.0dB and a 6dB bandwidth of ±17.5kHz. The device presents an impedance of 1kOhm and utilizes the standard FL series design.

Feature Summary

• Utilizes a compact SMD J-Lead package for automated surface-mount assembly
• Provides precise frequency selection with defined bandwidth characteristics
• Constructed as a ceramic resonator filter for stable RF performance

Applications

• AM radio receiver intermediate frequency filtering
• Signal processing in communication equipment
• Frequency discrimination circuits

Procurement Notes

Verify the exact part number against manufacturer documentation to ensure compatibility with specific circuit designs. Confirm that the 450kHz center frequency and 1kOhm impedance match system requirements. Check package dimensions for PCB footprint accuracy. Ensure sourcing from authorized channels to guarantee genuine Leading-Tech products covered by manufacturer warranties.

Selection Notes

Select this component when a 450kHz center frequency is required for AM applications. Consider the 4.0dB maximum insertion loss and ±17.5kHz bandwidth for signal integrity needs. The 3-SMD J-Lead package suits space-constrained designs requiring surface-mount technology. Verify impedance matching with surrounding circuitry to minimize reflection losses.

Part Context

This component belongs to the FL Series of KHz SMD Ceramic Filters produced by NextGen Components. It shares the Case 6560 physical form factor with other models in the family, such as the FL455K variants. The series is characterized by standardized pad configurations and consistent dimensional tolerances for reliable integration into electronic assemblies.

Replacement Considerations

The FL455K0000S003 is a related model within the same series but operates at 455.0kHz with different electrical parameters. Substitution requires verification of frequency compatibility and impedance matching. Direct replacement is not guaranteed without confirming specific circuit requirements against the alternative datasheet.
