FB450K0000L003

Overview

The FB450K0000L003 is a ceramic filter from the NextGen Components FB Series, designed for intermediate frequency applications. It operates at a center frequency of 450.0 kHz with a standard 6dB bandwidth of ±10.0 kHz and a maximum 50dB selectivity of ±20.0 kHz. The component features a 1.5 kOhm impedance and utilizes a 5-pin DIP configuration housed in Case 11070. Physical dimensions are specified as L11.0 x W7.0 x H8.0 mm.

Feature Summary

• Utilizes ceramic resonator technology for stable intermediate frequency filtering
• Provides defined bandwidth and selectivity characteristics for signal processing
• Features a compact 5-pin DIP package for through-hole mounting

Applications

• Intermediate frequency stages in communication receivers
• Signal processing circuits requiring 450 kHz filtering

Procurement Notes

Verify the specific bandwidth requirement against the datasheet, as variants exist with different selectivity profiles. Confirm that the 1.5 kOhm impedance matches the circuit design. Ensure the physical footprint aligns with the PCB layout for the 5-pin DIP case. Cross-reference the part number to distinguish between standard and narrow bandwidth versions.

Selection Notes

Select this component when a 450 kHz center frequency with a ±10.0 kHz bandwidth is required. Consider the 1.5 kOhm impedance for matching purposes. Evaluate the physical size constraints against the L11.0 x W7.0 x H8.0 mm dimensions. Compare against other FB series parts if tighter selectivity or different impedance levels are needed.
