Crystals Procurement Notes

Verify compliance requirements prior to procurement, as this specific part number may not adhere to RoHS standards depending on production batch variations. Confirm that the supplier provides official datasheets matching the Meritek MXJ series specifications. Ensure the ordering suffix aligns with the required packaging configuration, such as tape and reel quantities, to match assembly line requirements. Cross-reference the manufacturer's current product status to confirm availability and lead times before finalizing purchase orders.

Crystals Selection Notes

Select the MXJDHJI40M0 when designing circuits requiring a 40 MHz reference signal with surface mount compatibility. The 16 pF load capacitance must be matched with the oscillator circuit design to ensure accurate frequency generation. Consider the 80 Ohm ESR value when evaluating power consumption and drive level constraints. This component is appropriate for applications demanding high frequency stability across wide temperature variations, particularly in networking and mobile hardware environments.

Crystals Part Context

This component belongs to the Meritek MXJ series of passive quartz crystals. The series is characterized by low-profile surface mount packages designed for automated assembly processes. These units are engineered for high-frequency stability and reliability in consumer electronics and telecommunications. The MXJ series typically includes various frequencies and package types to support diverse circuit requirements.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 16 pF load capacitance, and HC-49SMD footprint. Verify that alternative components meet the same ±30 ppm tolerance and -40°C to +85°C operating range. Check for identical ESR values to prevent oscillator startup issues.
