Overview
The LTC455FW is a ceramic filter manufactured by Transko Electronics, Inc., designed for intermediate frequency (IF) applications in AM radio receivers. It features a center frequency of 455 kHz and utilizes a 4-SMD, J-Lead package. The component exhibits a minimum bandwidth of 6 kHz measured at the 6 dB attenuation point and possesses an impedance of 1.5 kOhm. This surface-mount device is engineered to provide stable signal filtering characteristics within standard electronic circuits requiring precise frequency selection.
Feature Summary
- Provides selective signal filtering for AM radio intermediate frequency stages
- Utilizes a compact surface-mount J-Lead package for automated assembly
- Ensures consistent performance with specified impedance matching
Applications
- AM broadcast receiver IF stages
- Consumer electronics audio processing circuits
- Industrial communication equipment signal conditioning
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference part numbers with authorized distributors to validate authenticity and current production status before finalizing procurement decisions.
Selection Notes
Select this component based on the required 455 kHz center frequency and 6 kHz bandwidth specifications for AM reception. Confirm that the 1.5 kOhm impedance aligns with the surrounding circuit design. Evaluate the 4-SMD J-Lead package dimensions against available board space constraints and thermal management requirements during the design phase.
Part Context
Transko Electronics, Inc. produces a range of ceramic filters for various frequency bands. The LTC455 series specifically targets the standard AM broadcast band intermediate frequency. These components are integral to maintaining signal integrity and selectivity in analog radio systems, distinguishing them from general-purpose resonators or oscillators.
