FB450K0000L116

Overview

The FB450K0000L116 is a ceramic filter manufactured by NextGen Components, designed for intermediate frequency (IF) signal processing applications. It operates at a center frequency of 450 kHz and features a bandwidth of 4.5 kHz with an impedance of 2 kOhm. The component utilizes a cube package configuration with five pins for surface or through-hole mounting. This specific model belongs to the CFTC U series, which supports cross-referencing with other market components sharing identical physical dimensions.

Feature Summary

• Utilizes ceramic resonator technology for stable intermediate frequency filtering
• Features a compact cube package design with five-pin configuration
• Supports interchangeability with standard market components of equivalent dimensions

Applications

• Intermediate frequency stages in AM radio receivers
• Signal processing circuits requiring 450 kHz center frequency
• Electronic equipment utilizing standard IF filter form factors

Procurement Notes

Verify the exact pinout configuration against your PCB footprint before integration, as the five-pin cube package may vary in terminal arrangement compared to legacy equivalents. Confirm that the 2 kOhm impedance rating aligns with your circuit's source and load requirements to ensure optimal signal transfer and minimal insertion loss. Cross-reference the physical dimensions L6.5*W6.0*H4.2mm with your enclosure constraints to guarantee mechanical fit within the assembly.

Selection Notes

Select this component when a 450 kHz center frequency with narrow 4.5 kHz bandwidth is required for audio or data demodulation. The 2 kOhm impedance makes it suitable for coupling with vacuum tube or specific transistor stages typical in vintage or specialized radio designs. Consider the five-pin cube package if space constraints allow for this specific form factor rather than smaller SMD alternatives.

Part Context

This part belongs to NextGen Components' ceramic filter portfolio, specifically the CFTC U series. These filters are engineered to replace older discrete crystal or mechanical filter solutions in modernized analog circuits. The series emphasizes dimensional compatibility with existing market standards, facilitating easier upgrades or repairs in established electronic designs without requiring significant layout modifications.

Replacement Considerations

The documentation indicates support for cross-parts with dimension L6.5*W6.0*H4.2mm and 3 pads in the market. Verify electrical equivalence, particularly the 450 kHz center frequency and 4.5 kHz bandwidth, when substituting with generic equivalents. Ensure the replacement maintains the 2 kOhm impedance characteristic to preserve circuit performance.
