LTC450IW

Overview

The LTC450IW is a surface-mount ceramic filter manufactured by Transko Electronics, Inc., designed for AM radio applications. It features a center frequency of 450 kHz and a bandwidth of 2 kHz. The component has an impedance of 2 kOhm and an insertion loss of 6 dB. It is housed in a 4-SMD, J-Lead package.

Feature Summary

• Designed specifically for AM radio signal processing
• Utilizes ceramic technology for stable filtering performance
• Surface-mount construction for automated assembly

Applications

• AM broadcast receiver circuits
• Intermediate frequency filtering in communication devices
• Consumer electronics requiring AM demodulation

Procurement Notes

Verify the specific suffix 'IW' against official Transko documentation to confirm package type and termination style. Ensure compatibility with existing PCB footprints for 4-SMD J-Lead components. Cross-reference part numbers with authorized distributors to avoid counterfeit units. Confirm RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a 450 kHz center frequency and 2 kHz bandwidth are required for AM applications. Consider the 2 kOhm impedance match with preceding stages. Evaluate the 4-SMD J-Lead package dimensions against available board space. Compare insertion loss characteristics with alternative filters to ensure signal integrity meets system requirements.

Part Context

Transko Electronics produces a range of ceramic filters for various intermediate frequencies. The LTC series typically targets AM and FM broadcast bands. This specific model fits within their surface-mount portfolio, offering compact solutions for modern electronic designs requiring reliable frequency selection.

Replacement Considerations

Check for direct substitutes like LTC450BU or LTC450GW from the same manufacturer. Verify that any replacement maintains the 450 kHz center frequency and compatible impedance. Ensure pinout and mechanical dimensions match the original design constraints.
