Procurement Notes

Verify the specific packaging suffix required for your production line, as this part number may be available in bulk or reel configurations. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to ordering. Ensure the selected variant matches the required surface mount footprint dimensions and terminal style for your PCB layout. Cross-reference the datasheet revision date to confirm parameter accuracy against current manufacturing standards.

Selection Notes

Select this component when a 16.384 MHz reference signal is required for digital logic or microcontroller systems. The ±50 ppm stability suits applications where moderate frequency precision is acceptable. Consider the 16 pF load capacitance requirement to ensure proper circuit oscillation. Evaluate the -10 °C to +60 °C temperature range against your operational environment constraints before finalizing the design.
