LTC455GW

Overview

The LTC455GW is a ceramic filter manufactured by Transko Electronics, Inc., designed for AM radio receiver applications. It features a center frequency of 455kHz and utilizes a 4-SMD, J-Lead package. The component provides selective frequency filtering with a minimum bandwidth of 7 kHz at the 6dB point and exhibits an impedance of 1.5kOhm.

Feature Summary

• Provides selective frequency filtering for AM radio receivers
• Utilizes a compact surface-mount J-Lead package design
• Engineered for high-quality signal processing in consumer electronics

Applications

• AM radio receiver circuits
• Intermediate frequency (IF) filtering stages
• Consumer audio equipment signal processing

Procurement Notes

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

Selection Notes

Select this component when a 455kHz center frequency is required for AM broadcast band applications. Consider the 4-SMD J-Lead form factor for automated assembly processes. Evaluate the 7kHz bandwidth specification against desired selectivity requirements. Verify impedance matching within the circuit design to ensure optimal signal transfer and minimal insertion loss.
