Crystals Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the received part matches the specific E1SJA18-9.216M TR designation, including suffixes indicating tape and reel packaging. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Cross-reference datasheet revisions to confirm current electrical specifications and mechanical dimensions before integration into final assembly processes.

Crystals Selection Notes

Select this component when a 9.216 MHz reference is required for surface mount PCB layouts. The 18 pF load capacitance must align with the host oscillator circuit design to maintain frequency accuracy within the specified ±15 ppm tolerance. Consider the physical dimensions of the short HC-49/UP package for board space constraints. Verify that the operating temperature range of -40°C to +85°C meets environmental demands of the target application.

Crystals Part Context

This part belongs to the Ecliptek E1S series of surface mount crystals. The series offers various frequencies within the 10 MHz to 54 MHz range using standardized packages.
