Resonators Procurement Notes

Verify the specific revision status and lifecycle stage before procurement, as availability may vary across distributors. Confirm that the 40 Ohm impedance and 40 MHz frequency align with the target circuit design requirements. Ensure the through-hole package dimensions match the printed circuit board layout constraints. Cross-reference the manufacturer datasheet for any updates regarding compliance or packaging changes.

Resonators Selection Notes

Select this component when a low-cost, high-stability timing source is required for through-hole assembly processes. Consider the ±0.3% stability specification for applications sensitive to frequency drift over temperature variations. Evaluate the 40 Ohm impedance against the driving circuit capabilities to ensure proper oscillation startup. Compare performance metrics against crystal alternatives if higher precision is necessary for the specific application environment.

Resonators Part Context

This part belongs to TDK Corporation's FCR series of ceramic resonators, which are widely used in general-purpose electronic devices. The series offers various frequency options and package types to suit different design needs. As a passive timing component, it replaces more complex oscillator modules in simple clocking applications, providing a balance between performance and manufacturing cost.

Resonators Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 40 Ohm impedance, and radial through-hole package. Verify compatibility with existing circuit loading capacitance. Check for equivalent stability and tolerance ratings from other manufacturers offering ceramic resonators.
