Crystals Procurement Notes

Verify the specific suffix codes against official Siward documentation to ensure exact electrical parameters match design requirements. Confirm package orientation and pinout definitions prior to PCB layout finalization. Request updated lead time information directly from authorized distributors as manufacturing schedules may vary. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet to maintain component reliability during soldering processes.

Crystals Selection Notes

Select this component when a 40 MHz reference with tight ±7 ppm stability is required in minimal board space. The 6 pF load capacitance must align with the host oscillator circuit's input capacitance specifications. Consider the 35 Ohm ESR limit to ensure reliable start-up within the target application's voltage and temperature range. Evaluate thermal performance characteristics if the operating environment exceeds standard commercial temperatures.

Crystals Part Context

This part belongs to Siward’s line of miniature crystal resonators intended for portable and handheld devices. The 4-SMD no-lead format facilitates high-speed pick-and-place manufacturing processes. It serves as a critical timing element in digital signal processing and communication interfaces where precise clock synchronization is mandatory for data integrity and system performance.

Crystals Replacement Considerations

Cross-reference with Siward model XTL911100-M118-190 for similar 40 MHz specifications in a slightly smaller 1.2 x 1.0 mm package. Verify mechanical compatibility and electrical equivalence before substitution. Consult official replacement guides to confirm parameter alignment.
