Crystals Procurement Notes

Verify the specific suffix B2 against the official datasheet to confirm the exact temperature rating and packaging configuration. Ensure the 4 pF load capacitance matches the oscillator circuit requirements. Confirm RoHS compliance status for the specific batch. Cross-reference the manufacturer's latest documentation to validate availability and lead times before finalizing procurement.

Crystals Selection Notes

Select this component when board space is limited due to its small 1.2 x 1.0 mm dimensions. The 4 pF load capacitance requires matching with the host MCU's internal or external capacitors. Verify that the 130 kΩ ESR is compatible with the oscillator's drive level. Ensure the operating environment stays within the specified -20°C to +70°C range.
