FM455K0000S115

Overview

The FM455K0000S115 is a ceramic filter manufactured by TGS, designed for intermediate frequency applications. It features a center frequency of 455 kHz and a bandwidth of 12 kHz. The component exhibits an impedance of 1.5 kOhm and is housed in a compact 4-SMD J-Lead package with dimensions of 12.0 mm length, 6.5 mm width, and 3.0 mm height. This surface-mount device belongs to the CFTC W Series and utilizes four pads for connection.

Feature Summary

• Provides precise signal filtering at the standard 455 kHz intermediate frequency
• Utilizes a compact surface-mount design for automated assembly integration
• Constructed as a robust ceramic resonator element for stable performance

Applications

• AM radio receiver circuits
• Intermediate frequency stages in communication equipment
• Signal processing modules requiring 455 kHz selectivity

Procurement Notes

Verify the specific suffix S115 against the manufacturer's current datasheet to confirm pinout orientation and mechanical tolerances. Ensure compatibility with the target PCB footprint, specifically the 4-SMD J-Lead configuration. Cross-reference the impedance rating of 1.5 kOhm with the circuit design requirements to prevent mismatch losses. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed 455 kHz ceramic filter is required for AM demodulation or IF amplification stages. The 12 kHz bandwidth suits standard broadcast audio transmission needs. Consider the 1.5 kOhm impedance match for existing amplifier stages. The SMD form factor is suitable for space-constrained designs where through-hole components are impractical.

Part Context

This part belongs to TGS's CFTC W Series of ceramic filters. These components are engineered for cost-effective signal filtering in consumer electronics. The series typically offers high Q-factor characteristics relative to size. The FM455K0000S115 represents a specific variant optimized for surface-mount technology, distinguishing it from older through-hole equivalents in the same product line.

Replacement Considerations

Check for direct substitutes such as the FM455K0000S112, which shares similar physical attributes. Verify that any replacement maintains the 455 kHz center frequency and 12 kHz bandwidth. Ensure the alternative component supports the 1.5 kOhm impedance requirement. Confirm that the package type remains compatible with the existing PCB layout.
