Procurement Notes

Verify the specific manufacturer part number against official TGS documentation to ensure authenticity. Confirm that the 4-SMD J-Lead package matches your PCB footprint requirements. Check for any specific handling instructions related to ceramic components during assembly. Ensure the operating temperature range meets your application's environmental specifications before finalizing procurement.

Selection Notes

Select this component when a 455 kHz center frequency with 30 kHz bandwidth is required for AM applications. The 1.5 kOhm impedance must match the circuit design. The surface mount J-Lead package dictates the PCB layout constraints. Verify that the 4 dB insertion loss is acceptable for the system sensitivity requirements.

Part Context

This component belongs to the TGS ceramic filter family, specifically engineered for fixed-frequency filtering tasks. It serves as a passive electronic component used to isolate desired signals from noise in radio frequency circuits. The product line focuses on providing reliable performance for broadcast and communication standards.

Replacement Considerations

LT455EW is a documented substitute part number for this component series. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement maintains the same 455 kHz center frequency and 30 kHz bandwidth requirements.
