Crystals Procurement Notes

Verify component authenticity through authorized Murata distributors or direct channels. Request official datasheets and test reports to confirm compliance with specified electrical parameters. Ensure supply chain integrity to avoid counterfeit components that may exhibit degraded frequency stability or mechanical reliability.

Crystals Selection Notes

Select this component for applications requiring precise timing within standard industrial temperature limits. Ensure the host microcontroller supports the required load capacitance and drive levels. Avoid use in automotive powertrain or medical life-support systems due to lack of high-reliability certification. Confirm PCB layout guidelines are followed to minimize stray capacitance.

Crystals Part Context

The XRCGB series represents Murata's standard line of miniature crystal units designed for consumer and general industrial electronics. This specific model provides a balance between size reduction and performance, offering stable oscillation in compact form factors suitable for modern portable and embedded devices.

Crystals Replacement Considerations

Direct substitutes include other Murata models within the XRCGB family with identical frequency and package dimensions, such as XRCGB40M000F1S2BR0 or XRCGB40M000F1S2SR0. Verify that alternative part numbers match the specific load capacitance and stability requirements of the design.

Crystals FAQ

Is this component suitable for automotive powertrain applications?

No, Murata explicitly prohibits the use of this component in automotive power control, aerospace, or medical life-support scenarios due to insufficient reliability certifications for these high-safety environments.

What are the soldering limitations for this crystal unit?

The component can withstand up to two reflow cycles at 260°C for 5 seconds or hand soldering at 350°C for 5 seconds. Water-soluble fluxes must be avoided as they can penetrate the non-airtight package and damage the internal crystal.
