FM455K0000S009

Overview

The FM455K0000S009 is a surface-mount ceramic filter manufactured by NextGen Components, designed for intermediate frequency applications in AM radio receivers. It features a center frequency of 455 kHz and an impedance of 1.5 kOhms. The component utilizes a 4-SMD J-Lead package with dimensions of approximately 6.5 mm x 6.0 mm x 4.2 mm. Key electrical specifications include a maximum insertion loss of 5.0 dB and a minimum 6dB bandwidth of ±6.0 kHz, ensuring effective signal filtering for standard broadcast frequencies.

Feature Summary

• Provides precise frequency selection for AM broadcast bands using ceramic resonator technology
• Utilizes a compact surface-mount J-lead package for automated assembly integration
• Delivers controlled insertion loss and bandwidth characteristics for signal integrity

Applications

• AM radio receiver intermediate frequency stages
• Consumer audio equipment signal processing
• Broadcast reception circuitry

Procurement Notes

Verify the exact physical dimensions and lead configuration against the official datasheet before PCB layout finalization. Confirm that the 1.5 kOhm impedance matches the surrounding circuit requirements to ensure proper matching and minimal signal reflection. Check for RoHS compliance status if required by specific manufacturing standards.

Selection Notes

Select this component when a 455 kHz center frequency is required for AM demodulation circuits. Ensure the design accommodates the 4-SMD J-Lead footprint and thermal constraints associated with surface-mount ceramic filters. Compare insertion loss specifications against alternative suppliers to optimize overall receiver sensitivity.

Part Context

This part belongs to the FM Series of KHz SMD Ceramic Filters from NextGen Components. The series supports cross-referencing with other market components sharing similar L6.5*W6.0*H4.2mm dimensions. It is distinct from SAW filters and quartz crystals, offering a cost-effective solution for fixed-frequency filtering applications.

Replacement Considerations

Cross-reference with other 455 kHz ceramic filters in the 12065 type form factor. Verify compatibility with existing board space and soldering profiles. Ensure substitute parts maintain the same 1.5 kOhm impedance and J-lead terminal style to avoid redesign.
