LTC455EU

Overview

The LTC455EU is a surface-mount ceramic filter manufactured by Transko Electronics, Inc., designed for AM radio applications. It features a center frequency of 455 kHz and a minimum bandwidth of 7.5 kHz at the 6 dB point. The component operates with an impedance of 1.5 kOhm and utilizes a 3-SMD, J-Lead package configuration. Its physical dimensions are specified as 0.236 inches in length by 0.276 inches in width (6.00 mm x 7.00 mm). This device serves as a precision intermediate frequency filter for signal processing.

Feature Summary

• Precision ceramic construction for stable intermediate frequency filtering
• Optimized for AM broadcast band reception applications
• Surface mount design with J-lead termination for automated assembly

Applications

• AM radio receiver intermediate frequency stages
• Consumer audio equipment signal processing
• Broadcast receiver circuitry

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement source provides valid RoHS compliance data. Cross-reference the part number with the latest datasheet to confirm package type and impedance specifications before ordering.

Selection Notes

Select this component when a 455 kHz center frequency is required for AM signal demodulation. Consider the 1.5 kOhm impedance match with preceding amplifier stages. Evaluate the 3-SMD J-Lead footprint compatibility with existing PCB layouts. Confirm that the 7.5 kHz bandwidth meets the desired audio fidelity requirements for the target application.

Part Context

Transko Electronics specializes in passive components including ceramic filters and resonators. The LTC series represents their line of surface-mount ceramic filters intended for communication and audio applications. These components replace older through-hole designs to facilitate modern surface-mount technology manufacturing processes.

Replacement Considerations

Consult official substitution guides for compatible equivalents. Verify that any alternative maintains the 455 kHz center frequency and 1.5 kOhm impedance. Ensure mechanical footprint compatibility with the 3-SMD J-Lead package.
