Procurement Notes

Verify the specific ordering suffix to ensure correct frequency and tolerance specifications. Confirm package dimensions match the target PCB footprint. Check datasheet for load capacitance requirements to ensure proper circuit tuning. Validate that the component meets the required environmental operating conditions for the intended application.

Selection Notes

Select this component when a 45 MHz center frequency with 15 kHz bandwidth is required. Ensure the design accommodates the specified 3 dB insertion loss. Verify compatibility with the 6-SMD no-lead package style. Consider the ceramic construction properties for thermal and mechanical stability in the final assembly.

Part Context

This part belongs to the ECS-75SMF series of miniature SMD monolithic crystal filters. The series is characterized by its small physical size and high Q-factor performance. These filters are designed to replace larger through-hole components in modern electronics manufacturing processes requiring surface-mount technology.

Replacement Considerations

Cross-reference with other ECS-75SMF variants for different frequencies or tolerances. Verify pinout compatibility if substituting with similar packages from other manufacturers. Ensure electrical parameters such as bandwidth and insertion loss meet the original design specifications.
