• Utilizes a robust cube package design with five-pin configuration
• Offers specific impedance matching at 1.5 kOhm for circuit integration

Applications

• Narrow-band filtering in communication systems
• Signal processing in receiver circuits
• Intermediate frequency filtering in radio equipment

Procurement Notes

Verify the exact tolerance variant required, as specifications list multiple options including ±1.0%, ±5.0%, ±7.50%, and ±20.0%. Confirm the package type matches the PCB footprint requirements. Ensure compatibility with the target operating temperature range. Cross-reference the part number suffix to guarantee the correct impedance and bandwidth characteristics for the specific application design.

Selection Notes

Select this component when a fixed 455 kHz center frequency is required for intermediate frequency stages. Consider the 7.5 kHz bandwidth for applications demanding high selectivity. Evaluate the 1.5 kOhm impedance against source and load impedances to ensure proper matching. Choose based on the necessary tolerance level for the specific circuit precision requirements.

Part Context

This part belongs to the ceramic filter category from NextGen Components, which specializes in quartz crystals, SAW filters, and resonators. The FB series typically serves as fixed-frequency filters for analog and digital signal processing. These components are distinct from active filters or tunable solutions, offering passive, stable frequency selection without external power.

Replacement Considerations

The FB455K0000L112 is a documented alternative featuring a 12.5 kHz bandwidth and 1.5 kOhm impedance. Verify if the wider bandwidth meets the application needs. Check pinout compatibility and physical dimensions before substitution.
