Resonators Procurement Notes

Verify the specific datasheet version for the ECS-HFR-40.00-B-TR to confirm current RoHS compliance status and lead time requirements. Ensure the ordering suffix matches the required packaging format, such as cut tape, as specified in the official manufacturer documentation before finalizing procurement orders.

Resonators Selection Notes

Select this component when a cost-effective, compact clock source is required for microcontrollers or simple logic circuits. The integrated capacitor simplifies PCB layout compared to discrete crystal oscillators. Verify that the ±0.5% tolerance meets the system's timing accuracy requirements and that the 8 pF internal capacitance aligns with the host device's input specifications.

Resonators Part Context

This part belongs to the ECS-HFR-B series of ceramic resonators designed for general-purpose timing applications. The series provides a balance between performance and cost, offering better stability than LC oscillators while being more affordable than quartz crystals. The 40 MHz variant is commonly used in systems requiring moderate precision clock signals.

Resonators Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 8 pF built-in capacitance, and 3-SMD non-standard package dimensions. Verify equivalent frequency tolerance and operating temperature range. Cross-reference with other manufacturers' ceramic resonator series offering similar form factors and electrical characteristics.
