Crystals Procurement Notes

Verify the specific load capacitance requirement of your target circuit matches the 8 pF specification. Confirm that the operating temperature range of -20°C to +70°C aligns with your environmental conditions. Ensure the PCB layout accommodates the 3215 package dimensions. Cross-reference the datasheet for exact electrical characteristics before finalizing the design.

Crystals Selection Notes

Select this component when a standard 18.432 MHz frequency is required for audio or telecommunication interfaces. Consider the ±30 ppm tolerance if higher precision is not necessary. The 8 pF load capacitance must match the oscillator circuit's input capacitance. Evaluate the -20°C to +70°C range against your application's thermal profile to ensure reliable operation under expected conditions.

Crystals Part Context

This part belongs to the 7V series of crystals from TXC Corporation, which are characterized by their small form factor and reliability. The 7V series is widely used in consumer electronics and industrial applications where space efficiency and consistent performance are prioritized. It represents a standard solution for generating common frequencies like 18.432 MHz in compact devices.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz crystals with identical 8 pF load capacitance and similar package dimensions. Verify that alternative parts meet the same ±30 ppm tolerance and 60 Ohms maximum series resistance specifications. Ensure compatibility with the existing oscillator circuit design regarding drive level and load capacitance requirements.
