LTC450DU

Overview

The LTC450DU is a ceramic band-pass filter manufactured by Transko Electronics, Inc., designed for AM signal processing applications. It features a center frequency of 450 kHz with a bandwidth of 3 kHz. The component operates within a frequency range of 0.4485 to 0.4515 MHz and presents an impedance of 1.5 kOhm. It is housed in a compact 3-SMD, J-Lead package, suitable for surface-mount assembly in communication equipment requiring precise intermediate frequency filtering.

Feature Summary

• Provides selective band-pass filtering optimized for AM broadcast signals
• Supports signal bandwidth up to 3 kHz for extended communication range
• Utilizes ceramic construction for stable performance at 450 kHz center frequency

Applications

• AM radio receiver intermediate frequency stages
• Communication equipment signal conditioning
• Broadcast receiver filtering circuits

Procurement Notes

Verify the specific manufacturer part number against official Transko Electronics documentation to ensure compatibility. Confirm that the 3-SMD J-Lead package matches your PCB footprint requirements. Check datasheet specifications for impedance and bandwidth tolerances relevant to your circuit design before procurement.

Selection Notes

Select this component when a 450 kHz center frequency with 3 kHz bandwidth is required for AM applications. Ensure the system supports 1.5 kOhm impedance matching. The SMD J-Lead package dictates specific layout constraints for surface-mount technology integration.

Part Context

This component belongs to the ceramic filter category from Transko Electronics, Inc. It is distinct from oscillator products like the TSM32 series found in general searches. The LTC450DU serves as a passive frequency-selective element rather than an active timing device.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify pinout and electrical parameters carefully if considering alternative manufacturers.
