Crystals Procurement Notes

Verify the specific package dimensions and electrical parameters against the official Eaton Electronics datasheet prior to procurement. Ensure that the load capacitance requirements of the target circuit match the 12 pF specification of this component. Confirm compatibility with the specified operating temperature range for the intended application environment. Cross-reference the manufacturer part number to avoid substitution errors during supply chain management.

Crystals Selection Notes

Select this component when a 27 MHz reference signal is required with tight initial tolerance specifications. The 1210 package size offers a balance between performance and board space efficiency compared to larger through-hole alternatives. Consider the 12 pF load capacitance requirement when designing the surrounding oscillator circuitry to ensure accurate frequency operation. Evaluate the thermal performance capabilities if the application involves significant ambient temperature variations within the specified range.

Crystals Part Context

This component belongs to the E3X series of crystal resonators from Eaton Electronics. The series is designed for general-purpose timing applications where moderate stability and compact form factors are prioritized.
