Crystals Procurement Notes

Verify the specific load capacitance requirement matches the target circuit design, as the component is specified for 18 pF. Confirm that the operating temperature range of -20°C to +70°C aligns with the environmental conditions of the intended application. Ensure the HC-49/US package dimensions fit the available PCB footprint before finalizing procurement.

Crystals Selection Notes

Select this component when a precise 85 MHz reference signal is required for through-hole assembly. Consider the 60 Ohm series resistance for impedance matching in the oscillator circuit. Evaluate the thermal stability requirements against the specified -20°C to +70°C range to ensure reliable performance under expected operating conditions.

Crystals Part Context

This part belongs to the TXC Corporation crystal family, designed for general-purpose timing applications. It serves as a passive frequency-determining element in electronic circuits. The HC-49/US form factor is widely used in legacy and industrial designs requiring robust mechanical mounting.

Crystals Replacement Considerations

Direct substitutes must match the 85 MHz frequency, 18 pF load capacitance, and HC-49/US package. Verify equivalent series resistance and temperature stability specifications to maintain circuit performance without redesign.
